Commandline/batch commands

Will execute commands from a batch file or directly from the command line
Examples:
asa_rcon --Settings:Host=localhost --Settings:Port=27020 --Settings:Password=AdminPassword --Settings:BatchPath=batch.txt

Or directly from the command line, delimited with semi-colons
asa_rcon --Settings:Host=localhost --Settings:Port=27020 --Settings:Password=AdminPassword --Settings:Command=/players;/save

Fixed an issue with not waiting for response from server after executing a command.

First release, very basic testing

Should support connecting/authenticating with a server. Tested a few commands.
