Identity lib

[Chuck Hagenbuch]

Jan - the Identity library has some code in it (in setSignature(), at least)
that relies on the $imp variable and $conf['hooks']['signature_hook']. This
needs to go away. The hook can either move to Horde or go away, but code in
Horde should _never_ rely on application specifics.
