- a load of bugfixes including:

- proper handling of invalid client connects, after 6 bad attempts in a 60 second period of time the IP address is blocked from the current game
  - Added check for invalid particles for tileset objects
  - Made messagebox wider in game mod menu
  - Fixed numerous threading issues discovered while testing on my 8 core CPU
  - a Little bit of rendering cleanup
