[Serusers] denying call based on country codes

[Iqbal]

yup thats where the problem comes, when you have complex rules for 
instance I have about 25 different packages for different countries and 
prefixes, eg some include UK mobiles others not, which means I have to 
breakdown into the prefix set for each mobile carrier. I am sure there 
is a better way, than grp and if else, I just havent worked it out :-)

Currently a user is linked to a grp, but there is no nice way of linking 
this grp table to the lcr table, or for that matter to dialed prefixes 
outside of the ser.cfg, unless someone has done a nice mysql lookup for 
this.
