check_tacacs_plus

the upper review made me think the script is buggy. To make it work, do what was mentioned above and add the nagios ip to the tacacs server, then it will result in authentication ok. in nagios it nagged about utils.pm not present. to fix this change the lib line in the script to point to utils.pm folder which should be that of the plugin.

Checks Tacacs+ nicely. As an FYI for users, it requires the perl module Authen::TacacsPlus. Also I had to modify the script to include use lib "$perl_library" Thanks.
