Qt4 - Sout: hide SAP options and ttl options when you don't stream. Adapt the label on the okButton according...

Qt4 - Main Interface: hiding menus does hide the controls and the statusBar. Still a lot of problems with that code, but at least it can be reverted.

Only basics options are done ( AVCodec + Muxer mainly ).
Two profiles are done. If you want to add more, then search "ADD HERE" in sout.cpp.
Reindentation of older code.

Patch by Jean-François Massol

Qt4 - Podcast dialog: Don't use the default OK/Cancel buttons, because they wouldn't be translated if we do it the default way. This does almost the same output. 

Qt4 - Right click on the header on the QTreeView for the playlist enables you to choose the columns you want to be shown. This removes also the code that was in the Model part since this is View Related. Ref #1282 (almost done).
There is still segfaults on close of VLC after that menu is triggered.

wxwidgets: fix crash in playlist due to change in meta behaviour (all metas used to retunr "" rather than NULL)

Note that on french locale floats are 0,x and not 0.x
