fixes the rss sub-filter with rss feeds using CDATA

* don't use 'ps' as suffix but 'mpg' like most other apps do. 'ps' can be confused with PostScript files on the Mac. In fact, the Finder tries to open our ps-files with Preview by default.

by access.
 * udp: force ts demux on payload 33 (:demux=dump will work)

    "I've added a bit of code to the UDP/RTP input, which assures that old
 or duplicate RTP packets are trashed. When the network performs packet
 reordering, only one discontinuity happens instead of 3 before - since
 the old packet is trashed. If multiple copies of the same packet are
 received, only one is used and all the others are trashed."
 

* allocate o_extended only if requested by the user (that's dirty, but prevents the access of freed objects while terminating) and save the extended-prefs as early as possible in the termination-process (directly after the vout and playlist shut down)

* Option to have extended interface by default (Closes: #232)
* Fix "floating" volume bar with wxMSW 2.6.X (Closes:#289)
* Enforce minimum vertical size (Closes:#360)
* Fix a font size problem on WX

* Add him to THANKS, obviously :)

* only save the affected modules (main, headphone, transform, adjust, invert, motionblur, distort, clone, crop, normvol, headphone_channel_mixer, macosx) -- thanks to zorglub for the help (closes #382)

open.cpp: unicode fix for ProbeDVD, ProbeCDDA, ProbeVCD

    -trigger the extended-panel to collapse completely before saving its position
    -save the prefs, if the extended-panel changed them previously (refs #382)
* extended.m: minor cleanups to make the stuff above possible (more cleanup needed, will follow later on)
* extended.nib & #.m: don't let the normvol-slider become zero, but use floats from 0.1 to 10.0 only

* use the ffmpeg-cvs-trunk from 09/27 and not the current one. This snap compiles finely on 10.2 and is used in the win32-port as well.

but it should not be necessary "thanks to" the vlc_symbols.h kludge

Implemented the retrieval of the versions, files and mirrors. Both the size and the mirrors aren't displayed yet, but stored. The 'Released On'-stuff was removed, since it isn't present in the xml actually. More to come. (refs #310)

* small script to move the preferences to Trash. You can change it by editing 'Delete Preferences.app/Contents/Resources/Scripts/main.scpt' in Xcode or the Script Editor. It is copied on the dmg by default. (thanks to dionoea for the idea)
