Updated code structure to spawn multiple power ups
Added code to spawn power ups based on the plist values. Also fixed bug where all the power ups respawned the sprint power up (due to copy/paste during restructuring of power up manager earlier :/)
Code added to create symmetric maze for both sides. Just set the "mirror" entry in the plist to YES.
