Performance improvement in FileView

This was a tricky one. Once again SheMov spinned at almost 100% CPU
usage. This time FileView::event() was the culprit. Because FileView
uses a QFileSystemModel it receives QTimer-Events every second.

Unfortunately a static_cast from QEvent::Timer to QEvent::Hover*
succeeds so we fetched the cursor position every second and tried to get
a QModelIndex. This obviously is quite expensive.

Fixed it by checking if e->type() is of QEvent::Hover* right at the
beginning of FileView::event().
