Move CHA, and ORS server commands into the FSession class.
Added the class FChannelSummary to hold the rudimentary channel information that's reported by CHA and ORS.
bugfix: Retrieving the channel list should no longer print random text to the console when debug mode is enabled. (Adding integers to string constants does not automagically convert the integer to a string.)
bugfix: Was not loading the character list correctly for ad-hoc channels.
