[MPlayer-dev-eng] Patch enabling ass_line_spacing

[Thomas Reitmayr]

Hi,
Using mplayer-20070824 I stumbled across the problem not being able to 
adjust the line spacing of ASS subtitles. The command line option 
-ass-line-spacing did not do anything.
In the code there seems to be a disconnect between the variable 
ass_line_spacing set via the command line and the value in libass' 
global_settings. The following patch should fix this (it might still 
need some beautification), please incorporate it if everything seems right.
Bye,
-Thomas
