* revert Pierre's fixes for 0.8.6b, as they aren't 10.3.9 compatible without further configure/makefile changes

* fixed ffmpeg's configure options and set the approbiate svn revisions for x264 (604) and libmatroska/libebml (1254)

* limit ffmpeg to revision 7400 to match 0.8.6a and prevent potential compatiblity issue. needs a bit of further testing

* added 2 boxes to the wizard to allow access to sout-transcode-soverlay with the GUI. needs further testing, but can't break anything. Additionally, the wizard's nib got converted to the diff-able xml-like format. refs #1005
