Acquirer 0.1 — Gather AA Server Information

[dlh]

Acquirer is a Ruby library used to gather server information from individual servers and the master server. All that works in respect to the master server currently is getting a login_accept message — it still needs work. Getting information from individual servers works fine — see the code below or acquirer/bin/server_info.
