Subject: [PATCH] elput: Add code to handle keybindings for vt switching

This patch makes elput handle receiving the key combinations for vt
switching and perform the actual switch itself. This is done so that
ecore_drm2, ecore_fb, etc, etc do not each need their own code to
handle vt switching.

@feature
