Better and unified comment style.

[VedVid]

For now, comments are kinda mess. Sometimes they uses multiple sentences, sometimes it's only one, long sentence with lots of ";". It would be more readable if space would be inserted between /* and first word.

Example:

	/*RenderWeights is created for debugging purposes;
	it clears whole map, and prints Weights of all nodes
	of graph, then waits for user input to reset;
	it's supposed to be called near the end of
	MoveTowardsPath method.*/

would become

	/* RenderWeights is created for debugging purposes  
	   It clears whole map and prints Weights of all nodes
           of graph, then waits for user input to reset.
	   It's supposed to be called near the end of 
           MoveTowardsPath method. */

Some work was already done in 6b0c8b5

But as a non-native speaker I can't be sure if my wording is understandable for other users.
