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

- Do not send TTL with IN IP6

* 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

* publish gvp support to launch-services (this was enabled in /trunk a long time ago, but forgotten to be back-ported to 0.8.6)

* download the SDL stuff from sourceforge instead of the bogus official server, as the SF park is much faster and more reliable

    - this allows native compilation on future darwin and current win32 releases
    - more recent library version (0.3.9 instead of 0.3.8)
    - [18618], [18552], [18530], [18525], [18524] (partially)
