Add Blue Coat, update Packeteer dictionaries

Based on public Documentation from Blue Coat, add their
VSA and update the Packeteer dictionary since they got
aquired by Blue Coat in 2008. Apparently some Blue Coat
products still make use of the Packeteer dictionary.

Based on following public documentation:
- KB4409 Configuring ProxyAV to authenticate
  via RADIUS for administrator login
- Packetguide 8.5, Configure RADIUS Server
Include the equallogic dictionary

It was previously added but not included.
