*	Drawing the grid has been moved to the Paint event where all the drawing will be handled.
*	Drawing has been restricted to the damaged regions only.
*	Grid colors has been changed to something more visible temporarily, to see if everything works fine.
*	For debugging purposes, the background colors change circularly.
*	We also log the coordinates on the console for debug purposes until everything will work correctly.

*	Corrected a bug in the grid drawing code which caused the grid lines to be always one pixel too short.
*	Cleaned up the grid drawing code by using shorter and more comprehensive names for the variables.
*	Removed the superfluous debugging code and reset the grid lines to their proper colors.
*	Added automatic build versioning into the `Makefile` and `main.cc`.
