* modules/gui/wxwindows/*: added subtitles options to the stream output dialog + add open directory menu to interface.

* rewind the stream to 0 if we found an id3 tag, but the flac demuxer ISNT the correct one. Same should be done for mp3 demuxer and any other demux that launches id3 module. But not today :D

* parsed info by mp3 is not retained between demux module probes since vlc_meta was introduced. so remove the old logic
This should fix the id3 parsing when you open an mp3.

inserting at a certain position is not yet possible.

put category in HTTP interface options

avi.c: make frame rate info available

WARNING: Since this parameter was ignored before probably there are a

   The change in the DTD is backwards-compatible.

* better support for multiple display selection on OS X. (Remembers last selection of screen between vouts)

* modules/misc/xml/*, include/vlc_xml.h: new xml_ReaderUseDTD() api to enable/disable DTD validation.

works with xtag for now due to lack of a DTD
