//==============================================================================
//	Created on: 09/04/2003
//	MaplistManager adds multiple maplist support to UT2004.  To ensure backwards compatibility,
//  it does not change the way the maplist system current works - instead, it enhances this
//  system by serving as the intermediary between the interface and the maplist used by the
//  game.
//  The only contact that MaplistManager has with the standard maplists are when
//    a) Creating the default list for a new gametype - it uses the value of the Maps array for
//       that gametype's maplist
//    b) When the user decides to "Use" or apply the maplist.  The maps in the custom maplist are
//       copied to the gametype's maplist class.
