New aspect prescale code, parses aspect value from mpeg sequence header or commandline.

Removed X11_FULLSCREEN hack from mplayer.c and moved it to libvo/vo_xv.c.
Added support for nominator[:/]denominator float values in cfg-parser, thanks for the code by Steve Davies.
All around thanks to Steve for helping me understanding the whole stuff :)
