*** Merged Code from Multiplayer Branch Revision 2960 ***

- Virtual File System (VFS) by birdflu. This is needed for Multiplayer and is also used for Single Player. Very neat system :-) - Multiplayer Version 1.1 + some additional features and bugfixes * INFO: If you compile a new EXE and want to test, be sure to also use the latest SVN GameDir files in your JA2 install directory * git-svn-id: https://ja2svn.mooo.com/source/ja2/trunk/GameSource/ja2_v1.13/Build@2961 3b4a5df2-a311-0410-b5c6-a8a6f20db521
