~ Moved World models to Models package
-  Removed unnessecary imports
+ Fixed some imports according to the move of the World models to the Models package
~ Changed the reward give functionality back to the WorldController as it seems to be meer suitable to let the reward be monitored/controlled through the WorldController
+ Added functionality to the corresponding model of the WorldController to do this
~ Changed the way how the reward type is monitored; instead of a boolean for positive or negative, now an integer with 1 for positive, 0 for none, -1 for negative
~ Relocated some functionality of the MainFrameKeyController to the WorldController
- Removed an import in the MainFrameController for the MainFrameKeyController
+ Added two run timers in the MainFrameController and WorldController that can be turned on and off using public functions instead of doing this in a parent class
+ Added boolean into the MainFrame and World that monitors whether its respective controller runs the added timers

! Do not that currently if the MainFrame is not turned on BEFORE the World some weird things can happen
- Removed some unused InfoBar lines in World that were left over of the original environment
~ Commented out some seemingly unused lines in WorldView

! This should have made the gird resize according to the WorldView panelsize, however this is not the case (yet!)
