avoid unwanted clicks on touch-screen. 

avoiding the un-wanted clicks with touch-screen devices (especially if
they aren't so precise); it basically allows to set a time delay to be
awaited (pressing over an icon) before sending a "selected" callback.

Thanks to this, it could be needed a longer pressure to select an item
in the file-manager; useful for embedded/touch-based systems.
