[PATCH] Better handle keybindings.

[Cosimo Cecchi <anarki lilik it>]

Hi Alex,

I've made a patch for bug #314431 [1], which fixes some issues when
keybindings set by the Nautilus main window could override the one set
by the currently focused widget. The code for this is taken and adapted
from Epiphany, so it should be tested and quite safe to use.
