macosx: implemented the Video category of the SimplePrefs panel. vout module and display device selectors are left as an exercise for the reader.

macosx: removed the 'macosx-embedded' setting. It's functionality is now controlled by 'embeded-video' (as defined in libvlc's main).

qt4-interface to use it. var_Change doesn't trigger callback so earlier
version about adding callback to it worked someway as intented only by
luck ;)

something fishy in here because seems that inputmanager doesn't get
variable callbacks regarding input-rate from /src/input/input.c. 
Slider worked because we set ourself that rate-variable, or atleast it seems
so.

Thanks to André Weber for those 3 patches.

Add a variable to the video output core which is triggered after each crop parmaeters change.

macosx/frontrow_plugin: VLCMediaListController, display a mediaListAspect in a FrontRow list. To get a service discovery in frontrow go into VLCAppliance.m -applianceController and uncomment the right part.

* extras/contrib/src/x264-svn-win32.patch: add threads count debug info to check how many threads x264 will use (threads 0 is default and will make libx264 automagically set threads = cores * 1.5) and whether win32-pthread works as expected (libx264 can report not compiled with pthread and forces threads = 1)

Qt4 - small fixes... Remove one redondant connect, block the access to the speedSlider if there is no input.

Qt4 - Open Disk. Provide a button to eject the disk drive. has been requested twice on the forum. Maybe should be moved somewhere else. The intf_eject doesn't seem to work on my computer now...
