An updated version of MCCP compression to take into account v2. There are only two total differences between v1 and v2. Version 1 had an unterminated sequence, and the use of COMPRESS2 = 86. Made this because I noticed a few clients were starting to only support version 2. It's patched against stock bpl20. The only part I'm not positive on is the handling of a client which tries to turn off compression once begun. I went with the idea that a COMPRESS stream will send IAC DONT COMPRESS and COMPRESS2 will send an IAC DONT COMPRESS2, but the spec is unclear except during initial negotiation.
