Frameworks: recents rearrangement recents + fixes

Recents was and is a crap...already from AOSP...whatever
to avoid animation conflicts with the RAM bar it is moved up.
Due a lot user requests the clear recents is not bottom left
Recents container is now reduced and on bottom off ram bar
so that no visual overlap glitch exist any more. As well the
recents scrollview is more stable and now small 1dp glitches like
the original AOSP implementation. Code cleanup
and some code arrangements.

cheers

Framework: CustomToggle Improvements (!Advanced)

Remove advanced Preference in favor of:
        If click = null, use longclick icon.
        This is all Advanced vs Basic was, really.
        User confusion might ensue, but ultimately,
        Exact same ability if you set click to null.
        This also clarifies the ShouldCollapse
        Preference through correlation of it not
        Collapsing on-click in basic.
        Also refresh Icons ondemand.

Framework: Fix recents animation bug for all

Sometimes doing some other stuff bring ideas up to solve
problems. Google uses a dirty preload animation hack to
animate recents right....we can do the same just more
generalized.....due that all places (hw keys, navbar, SlimPie
and navring) are calling toggleRecents() I implemented the fix
now there to solve it in general. Due of that this commit
reverts commit 20a905c96c6a897226ad2e5a47c9c6b39a0ef040.
as well

cheers
