Settings: SlimRecents: user configurable default expanded mode (2/2)

A lot requests to customize the default behaviour
auto = like it is now....dependend on the overlay the first tasks are expanded other collapsed
always = always all expanded
never = always all collapsed

Of course still user changes directly in the recent panel counts more then the default settings
behaviour

PS:
- capitalize strings

Settings: apple can do...we can do as well

incredible apple engineers speeded up the overall UI and reduced per default slightly
the animation scales. Well we do as well and reduce it from 1 to 0.75...smooth, looks well
and does not break anything
