Bug 9569: Fix AutoLocation - handle .* for subnets

The example in branches.tt is:
  Can be entered as a single IP, or a subnet such as 192.168.1.*

But actually the regex in C4::Auth does not handle subnets.

Test plan:
0/ Apply all the patches
1/ Switch AutoLocation on
2/ Define a subnet (192.168.0.* if your ip is like 192.168.0.X) in the IP
range of your library
3/ Log in on the staff interface
=> Should work
