restore some game functionallity

* i'm gradually restoring game functionality with the new modules design, though still a lot to do
* you can reload all scripts and modules using Ctrl+R shortcut while playing (finally! this is the reason of all this rework)
* a bunch of fixes, but new regression too :P
* fix performance issue that could lead freezes in the client in older machines
* completely new game module with new design
* fix crashs in map render
* remove uigame.cpp (now every game input is via lua)
* enable DEBUG macro by default, with it you are able to view any possible lua leak while running
