I've made this little patch for 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.

Subject: [PATCH 1/2] e_fm2 single-click delay support
This patch allows to set a delay to select an item in the e_fm2 if
it is using the single-click mode. Thanks to this, it could be needed
a longer pressure to select an item in the file-manager; useful for
embedded/touch-based systems.
