s/lockdown/disable in GConf key descriptions

[Luca Ferretti <elle uca libero it>]

If I'm right by now only Epiphany and gnome-panel implement lockdown
features.

Ephy uses "disable" in GConf key descriptions[1], gnome-panel
"lockdown"[2].

IHMO the Ephy way is better, and easier to translators. I'm not saying
that gnome-panel have to use "disable", but just a more descriptive and
less technical verb then "lockdown".

BTW please note that gnome-panel as already an action called "Lock" for
applets, and, for example, in Italian is a tricky job distinguish lock
from lockdown.

Comments, opinions?

protocols are http: and https:" for

[2] i.e. "Complete panel lockdown" for /apps/panel/global/locked_down:
this one can became "Disable panel editing" or similar
