[Users] IP based register allow

[ibrahim.tunali at comturk.com]

Hi,

I want to permit IP based REGISTER requests so i created register.allow 
and register.deny. But i couldn't success permission to REGISTER.

Also I check register.allow and register.deny file on SVN trunk but it's 
very simple.

register.allow;
"^sip:555[0-9]{7}@" : 1.2.3.4

register.deny;
ALL:ALL
