Before retake

The last ever voxeliq source code before retake version.

v0.2

• More code cleanup & bug-fixes.
• Improved mesh optimization (http://www.int6.org/development/voxeliq-engine/improved-mesh-optimization/)
• Added unit tests for engine.
• Implemented a basic & buggy console & commands subsystem.
• Implemented a very primitive blocky sky & clouds.
• Improved logging & configuration facilities.
• Implemented platform manager that can identify running platform & frameworks.
• Added vsync & fixed timesteps options to config.ini.
• Log targets are now also configured in config.ini now.
• Added an engine.log file log-target.
• Fixed a bug where chunks in cache-range were not lightened as expected.
• Added cache-range checks.
• Improved Chunk's and Block's string representation.
• Fixed issue #18 where view-range value was incorrectly used when calculating cache width and height. Instead cache-range had to be used and fixed so.
• Fixed Chunk.FastSetBlockAt() so that minus world coordinates also work. ChunkCache.GetChunk is also fixed for minus values. Player is now spawned at 0,0.
• Moved chunk statistics calculation to ChunkCache.Draw() - finally the values are preserved, which eventually fixes the chunk debug graph bugs.
• Added chunk removal queue debug-graph.
• Fixed a tiny capture mouse & mouse visibility bug.
• Moved ini-file based config-classes from Engine to Client project. Engine is now free of both Nini reference and the ini file itself. The actual game can do what-ever he wants when he supplies parameters to EngineConfig.
• The Engine ctor() will now throw an exception when additional instances created (Discussed in issue #43).
