Settings: SlimRecents scaling + lefty mode (3/3)

    - Add scaling mode....user can scale the overall size down (especially for the
      user with stock dpi requested)

    - Add lefty mode. Recent panel shows up on the left edge instead of the right edge
      for left handed people.

Both are one time accesibility settings. So we put it there.

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
