** Big Maps Projects code (incl. Multiplayer v1.5 **
**********************************************************
- Merged Big Maps Project code from BMP+MP trunk (Revision: 3340)
o Complete SVN Revision history: https://81.169.133.124/source/ja2/branches/Wanne/JA2%201.13%20MP
- Before THIS merge, I made a branch of the existing 1.13 source
o SVN Branch: https://81.169.133.124/source/ja2/branches/JA2_rev.3336/src
- Removed old VS 6.0 and VS 2003 project and solutions files, because compilation is broken long time ago
- I will add VS 2010 projects and solution file in the next few days
