[PATCH] Allow the user to restrict the RC5 address

Mauro,

This patch allows users with multiple remotes to specify an RC5 address for a
remote from which key codes will be accepted. If no address is specified, the
default value of 0 accepts key codes from any remote. This replaces the current
hard-coded address checks, which are too restrictive.
