workspaceThumnails: Add :should-show property

Browse Source 
We currently have two components that show or hide the minimap:

 - the thumbnails hide themselves in case of a single static workspace
 - overview controls show the minimap when no search is active

That obviously doesn't work correctly.

To fix this, change thumbnails to set a new :should-show property instead
of the visibility, and let the overview controls take it into account
when changing the visibility.
