Mplayer PP7 (Deblocking) filter port

[JohnDoe]

I have ported the above filter to AviSynth 2.5. Incidentally, it is been my first Avisynth filter. I think it can be improved significantly. Feel free to optimize / fix / improve. Possibly someone can put a link to the avisynth plugin website. Due to time constraints, I will currently not able to deal with it.

I'll add it to the wiki whenever a mod approves the attachment.

Missed this last night. Looks interesting.

Arguments are: DeblockPP7(clip, int "qp"=5, str "mode"="medium", bool "mmx"=True)

Looks a bit different from Deblock(). Source doesn't look difficult to adapt to avs2.6 or x64, though the inline assembly would have to go.

Since the filter does not come with documentation I created a page for it on the wiki. It's basically a copypasta from the FFmpeg pp7 documentation (http://www.ffmpeg.org/ffmpeg-filters.html#pp7). I assume everything is relevant to the DeblockPP7 plugin (except for the auto qp setting).
