TACACS+ stuff

ios-xr bug: sends blank ip in conf t. tac_plus really should send an “unknown” for this. I’d submit a patch, but I’m no good at C. job == networker, job != programmer. Heasley strongly disagrees with me on this though. Even though I’m obviously right, I suppose someday I’ll have fix the parsing to ignore any options not sent. Till then:

v1.4:

Simple workaround: -i $address -fix_crs_bug. I advise you use it even if you don’t use ios-xr.
