Subject: A "fast search" implementation for all node views. Pressing any valid

A "fast search" implementation for all node views. Pressing any valid
unicode character will make ephy select the first entry begining
with that key, or the nearest match (with previous or posterior letters).
Fixes bug #116744 (http://bugzilla.gnome.org/show_bug.cgi?id=116744).
