Peter Schlaile c07bd1439a == Sequencer == 
This patch adds:

* support for proxy building again (missing feature from Blender 2.49)
  additionally to the way, Blender 2.49 worked, you can select several
  strips at once and make Blender build proxies in the background (using
  the job system)
  Also a new thing: movie proxies are now build into AVI files, and
  the proxy system is moved into ImBuf-library, so that other parts
  of blender can also benefit from it.
  
* Timecode support: to fix seeking issues with files, that have
  a) varying frame rates
  b) very large GOP lengths
  c) are broken inbetween
  d) use different time code tracks
  
  the proxy builder can now also build timecode indices, which are
  used (optionally) for seeking.
  
  For the first time, it is possible, to do frame exact seeking on
  all file types.
  
* Support for different video-streams in one video file (can be
  selected in sequencer, other parts of blender can also use it,
  but UI has to be added accordingly)

* IMPORTANT: this patch *requires* ffmpeg 0.7 or newer, since
  older versions don't support the pkt_pts field, that is essential
  for building timecode indices.
  
  Windows and Mac libs are already updated, Linux-users have to build
  their own ffmpeg verions until distros keep up.
