- Misc. fixes to TESTMASK/TESTLINE as reported by Phar Lap
  - Prevent TESTLINE from reporting k-lines twice
  - Show the actual k-line reason when reporting k-lines
  - Test the host part of a u@h mask against the client's sockhost field in TESTMASK
  - Added support for nick masks to TESTMASK
  - CIDR is to come in 7.3
