macosx: converted interface builder files from nib to the more modern xib file format, which smaller and more suitable for git

preliminary graphics..

macosx: icon set for the sidebar table taken from the Fogue icon set by Yusuke Kamiyamane, licensed as Creative Commons Attribution 3.0 unported (CC BY 3.0)

note: playlist view isn't connected to the side bar yet

macosx: fixed volume slider appearance in black intf mode and disable the track slider when appropriate

removed remnants of the Dudiak interface, added PXSourceList by Alex Rozanski (BSD-new licensed) which will be used for the new implementation, added a to-be-replaced png for the window's topbar

moved some elements around and renamed them within the 'Capture' tab

it's no longer called an 'iSight input', etc.

this also prepares a mainwindow object and includes some clean-up

This is a first step to re-organize the interface, more to come

no functional changes

macosx: remove the extended controls panel since all of its functionality is present in the * effects panels now

(effects other than the equalizer to be implemented)

fixed compilation of the intf

Note that this rework changes the current behavior: if VLC is in the background, the keys still control it, however if you start another key user (such as iTunes, QTP, etc.), it won't interfere and control the other app. That's why macosx-mediakeys-background was removed.

Thanks to Spotify for releasing their code.
