** Login GUI only appears when GUI is activated in conf and either Password or Accountname are not set
** Don't resize the Login Window
** Community Website button doesn't work yet, but Quit does
* Added a dynamic framerate limiter, though i think it's overkill. See comments in PseuGUI.cpp
* Changed std::cout to logdebug in the Image and MeshLoaders
* remove doodads from unused map tiles (after teleport or so)
* some render speedups (enabled automatic culling, but thats not enough. more optimizations must be done)
* commented out a line in the M2 loader, it was causing a crash (?!)
* added NormalizeFilename() in tools.cpp, please use this when formatting filenames for linux
* TODO: remove doodads that are too far away or if the map is changed. currently its using A LOT of graphics power
* corrected object placement
* corrected grid formulas
* update MyCharacter position when beeing teleported
* tested in dun morogh, stormwind, thrallmar and arathi basin, object placement on the map is just fine now ;)
* cleanups not yet done, old unused funcs are still there
* first preparations to correctly position gui camera on real location, not just somewhere. formulas are still crap, need some help here.
