v1.3

The following changes were made:

• Fixed bugs cause by new pathfinding system (from previous update)
• Further improvements to the pathfinding system (especially with recalculations of paths)
• Enemies will now only follow you for a certain amount of time since they last spotted you
• Fixed bug that caused the total amount of bullets to be 150, eventhough it was actually 180
• Improvements to the system for detecting if Enemies are stuck (and automatically fixing them)
