a bit space

Frameworks: SlimRecents: user configurable default expanded mode (1/2)

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
- correct code comment to new behaviour
PS
- fix typo

rebase
