Act on doubleClick in FileTreeWidget

When doubleclicking a picture in FileTreeWidget the pictureViewer
is shown. Doubleclicking a movie file launches the default movie
player.

Since PictureViewer is now used in FileSystemWidget and
ArchiveTreeView a global instance is needed. The appropriate place
for this is a singleton. Since we already had a singleton for
QAbstractItemModels I renamed it to SmGlobals and added a function
to return a PictureViewer object. Renaming it was quite easy
thanks to QtCreator's ability to rename variable names.
