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
