Initial commit of 7kmapgen. Based off 7kaa commit "9f10243 Translations: Remove note requiring a copyright transfer."
Changed name of project from 7kaa to 7kmapgen
Added Microsoft Visual Studio 2010 solution
vga_sdl: Remove Window creation and rendering code, leaving only backbuffers.

This way, 7kmapgen can run without the normal 7kaa graphics being displayed.
Made Battle and Sys members public so mapgen can call these to set up a game
OSYS: Remove debug_session, testing_session and scenario_cheat_flag checks
Added mapgen.cpp, the entry point for 7kmapgen
Hijacked 7kaa to run 7kmapgen instead. This is where the fun starts.
Map drawing: Don't draw the yellow zoom-rectangle on the map

We directly take the minimap from the 'running game'. Normally, the minimap indicates where the
current zoom is by drawing a yellow rectangle, which is now disabled for 7kmapgen.
Added .gitignore file for Visual Studio files
Added README for 7kmapgen
