Implement hover over movies

What started as an attempt to show a frame from a movie when hovering
over it, ended in a huge bugfix commit for hover related stuff. This
commit is definitely not atomic.

When hovering over a movie present on the filesytem a frame is shown.
The time frame is configurable. While digging into the code I noticed
some bugs.

Bugfixes:
* fix label for hove archive action. It was labeled for hovering over
directories in FSWidget.
* Hovering over directories didn't have an action. Also read the
appropriate value from QSettings.

Other:
* add icons for hovering over directories and hovering over movies
* replace SheMov::toggleHover(pics|some other) with a QSignalMapper
