*** 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 *
