Removed usage of String#unpack and Array#pack because Ruby 1.9.2 does…

… not support reading big-endian signed numbers on platforms that are natively little-endian.

Replaced pack/unpack with the BinData gem.
Added support for connecting to servers that implement protocol versions 10 and 11, but are backward compatible with version 9 (which is the highest version currently implemented in this gem).
