* modules/codec/a52.c: fixes and simplifications.

* modules/demux/ogg.c: had mistakenly got rid of the old i_dts = i_stop_date hack for text subtitles.

* modules/stream_out/transcode.c: get the mp4v vol data from the encoder. This will make the mp4 muxer happy transcoded mp4v.

* include/vlc_block_helper.h, modules/codec/a52.c: same as thedj ;)

* include/vlc_block.h, modules/codec/libmpeg2.c: re-added the discontinuity flag in block_t and re-enabled the discontinuity gestion in the libmpeg2 codec.
* include/vlc_block_helper.h: implemented bytestream reading helper functions for chained blocks.
* modules/codec/a52.c: modified to use the bytestream reading functions.
  The flexibility added by these functions makes the code simpler and better at detecting synchro code emulations.

* modules/misc/freetype.c: i_render_height and not i_window_height.

* modules/mux/ogg.c: always backup the vorbis/theora headers so we can resend them if we close/reopen the stream (chaining).
  fixes for text subtitles muxing.
* modules/packetizer/copy.c: support for text subtitles.

* include/os_specific.h: oops, fixed my last commit.

* include/os_specific.h, src/libvlc.[c,h], src/misc/win32_specific.c: new win32 specific option (--one-instance) to have only one instance of vlc running at once.
 Running another vlc (with --one-instance as well) will only transfer the requested playlist items to the first instance.

 * changed project name from 'vlc' to 'VLC'
 * excluded src/extras from the documentation
src/misc/variables.c, include/variables.h:
 * Doxygen-documented most of the vlc variables code

* modules/mux/ogg.c: proper fps and ogg packet granulepos when embedding mp4v/div3 (mplayer can play the file now).

* modules/codec/theora.c: don't forget to delete the sout instance.
* modules/mux/ogg.c: fix for embedding theora in Ogg.

* modules/mux/ogg.c: each ogg stream has to be cleared in OggCreateHeader().

* modules/demux/ogg.c, modules/codec/vorbis.c: misc small fixes.
* modules/mux/ogg.c: support for inserting/removing elementary streams on the fly (really handy for the --sout-keep option). This will produce a chained Ogg bitstream.

* modules/demux/ogg.c: support for DEMUX_GET_TIME. External subtitles files should work fine with ogg files now.

* modules/demux/ogg.c: support for 'chaining' (concatenated ogg streams).

* install-win32: cosmetic changes.
* configure.ac: forgot one include path for the mozilla plugin.

* modules/video_output/directx/*: some graphics card allow the creation of several overlay surfaces but can only display one at a time.

* src/misc/modules.c: removed an old win32 hack which was creating more problems than it was solving.

* modules/demux/ogg.c: reworked a bit. Ogg web radios should work again, vorbis audio tracks switching should work better as well.
* modules/mux/ogg.c: attempt at supporting theora.

* modules/codec/vorbis.c: wait for the first dated packet before starting decoding anything.

* include/main.h, src/libvlc.c, src/libvlc.h, src/misc/configuration.c: added a --config, --save-config and --reset-config option to the command line.
* modules/gui/wxwindows/preferences.cpp: fixed breakeage of "Save", "Reset" and SwitchAdvanced().

 The mozilla plugin seems to be working very well now, except that it doesn't receive mouse and keyboard events yet.

* src/playlist/playlist.c: fixed sorting

* configure.ac, mozilla/vlcshell.cpp, mozilla/support/npwin.cpp: mozilla plugin for win32 is finally working (well there's still work left).
* src/misc/modules.c: small clean-up and fixed --plugin-path on win32.

* modules/gui/wxwindows/preferences.cpp: compilation fix + cosmetic code clean-up
(indentations mainly).

	- Created the "General Settings" section
	- Added help strings in the two main sections,
		in the libvlc categories,
		and in the module capabilities

* modules/gui/wxwindows/playlist.cpp & wxwindows.h
	-Implemented random, loop and repeat using variables
	-The eye candy of the dialog box is not very good
	 but I have no idea how to improve it.
	-Focus on the currently playing item

* src/libvlc.h:
	- Added help strings for the libvlc categories
	- Changed a few "advanced" flag

* include/vlc_help.h:
	- Help strings for the two main sections
	- Help string for the module capabilities (both by Anil)

* po/*: updated potfiles with the new strings

Changes to Red Hat spec file:
- Added wxwindows, alsa, and skin support
- Fixed dependancies, specifically a version conflict of xvidcore

* modules/gui/macosx/output.m: updated part of the Stream output dialog
* modules/demux/util/sub.c: removed sub_detect() and moved the sub-file and
  sub-autodetect file options to src/input/input.c
* src/input/input.c: added the moved options and use them to add subtitle
  tracks.
* src/libvlc.h: description strings etc for sub-file and sub-autodetect-file
* src/input/subtitles.c: new subtitles_Detect() largely based on the
  code used by MPlayer. Adapted for coding style and structure differences.

The autodetect routine can now detect multiple subtitle files and assigns scores
based on their names. if they much well enough they are sorted based on their
score. It will then return this set, and they will all be added as SPU tracks
to the current stream. The (un)selecting of these tracks will need to be fixed
because they all get assigned the es id 0xFF currently.

* modules/gui/wxwindows/*: got rid of the close button in the fileinfo and playlist dialogs.

* modules/gui/wxwindows/*: we now have only 1 global "Advanced Options" checkbox in the preferences panel instead of 1 for each section (KISS).
