workspaceThumbnail: Rename show(), hide() and add new methods

Browse Source 
show() and hide() now slide the thumbnails in and out, respectively. The old
show and hide are now _createThumbnails and _destroyThumbnails. We only care
about these thumbnails while in the overview, so create them when entering and
destroy them on exit.
