login_radius possible changes.

[Brad Arrington]

Would it be possible to change login_radius.c actually raddauth.c so that:

1. The admin can change what port login_radius uses, such as the
old datametrics port. It is currently hard coded to radius(1812).

2. Make it so it does not try an empty password 2 times before it kicks back a
prompt asking for a password.

This is the diff/changes I had in mind.
