[WIP] Multi-window

This is a big work in progress, which currently has some bugs,
but begins to look okay.

You can already multitask a little bit, by using the
app switcher and long-pressing an icon, then select "Add to
Split View".
Last window touched gets the key focus.

Code is very ugly, I know. Don't merge it, don't use it
for now. Unless you want to make your code ugly.

Enjoy :)

fb: correct seeker fb style for 4.4

based on this commit https://github.com/SlimRoms/frameworks_base/commit/a845169c128c19825a69a0ebdf2e4d366fdd67ad

the idea was good but bad done. A middle in the night action lol.
Problem is that holo light themed app cannot handle the white seekbar of course
So add the complete seekbar into the Holo.Light switch to support both cases

Holo: white seekbar
Holo.Light: drak gray seekbar

fb: global menu follow new 4.4 UI

the sound indicator is still ICS blue...change it to white
In general we should consider to change all tab_selected
files into a Holo.Light switch due it is already defined in styles.xml

but thats work for our themer :p
