* 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

Closes #1031
It's probably unrealistic to fix this completely within the 0.8.6 branch

* 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

* back-port a fix, which allows sleeping or showing the screensaver when a video is paused [18565] and originally solved #963

* back-port Pierre d'Herbemont's patch to prioritize Cocoa menu short-cuts against VLC's native hotkeys [18766]

* back-port Pierre d'Herbemont's patch to animate vout-window resizing [18882]. the nib file was manually adapted by myself as the patch failed. I hope that I got everything. It works right now :)

* don't double free an object! Thanks to nivix for pointing me to the right direction and keeping to bug me about this. Fixes #978
