[Cin]Two more patches,one install script, second makes format gui button work for segmented profiles.

I hope rebase did not mess them ... 0019 patch is from our failed libtheora 1.2.0 update, but may be if user now links to thirdparty theora set to 1.2.0 it will be needed anyway? Postprocessing takes some time but makes image less blocky, normally. There are other patches, like setting bitexact flag on swscale operations, but I am not sure how useful they are ....
