Remove the Matroska keyframe/timecode loading code, as opening MKVs via Avisynth is dumb and didn't work very well anyway. Fix framerate reporting by actually bothering to read the video information before trying to use it. Kill the VFW wrapper and just put the code in the avisynth video source. If reading the keyframes from an avi file fails just warn the user rather than refuse to load the video. Originally committed to SVN as r5558.
