- faad2, goom2k4, libpng, ffmpeg (modified gibalou's patch and moved it to a win32-file)

* modules/gui/wxwidgets/playlist.cpp: if too many items are queued to be added to the playlist then it is quicker to just rebuild the whole playlist instead of inserting items one by one (fixes huge slowdown when using shoutcast).

  When it is set to "true", the window is automatically resized
  when the vout size changes.

Todo:
	Fix FLAC
	SDL patch by Meuh

* modules/codec/libmpeg2.c: when AR is forced by input, assume it is based on width/height, not display_width/height (required for broken DVDs).

aspect ratio (e.g. 1280x800, 1920x1200)

anything else than zoom=1.0 in Preferences.
Reworked it to always go through InitWindowsize() 

* sub elements can be moved up (positive values) and down (negative)
* force_crop'ed elements cannot be moves (usually only dvd menu's)
* works for spudec and subsdec
* if the margin / offset correction forces the picture out of the main picture, the offset is cropped so that the subpicture is still 100% visible.

* if we are certain we have a visualization module, don't try to open it as an audio-filter first. (fixes #416)

* macosx.m: renamed "Stretch Aspect ratio" to "Stretch video to fill window" to make the option's meaning a bit more clear (thanks to Jonas for the hint)
