Small Additions and bug fixes.

This update will include some small, yet nice, additions and some bug fixes.

Added: -An exit game button on the pause screen which will take you back to the main menu. -A quit game option on the main menu.

Fixes: -Fixed the issue of 'moon walking' and causing the player to not be able to shoot. -Fixed the pause/minimap not loading after collecting some items. -Removed some destroyable blocks from a specific map. -Hopefully fixed saving issues. For some reason, some players save files were being erased. *NOTE* This may still be a potential bug so please be sure to report it if it happens to you.
