Added Executable Downloads and Bug Fixes

Executables

Added zip files containing executables for the following platforms:

• Windows 64/32
• Linux 64/32
• Mac 64

Keep in mind that none of these are currently tested so I'm not sure if they will work. In the future, Linux and Windows executables will be tested before release but there will never be tests for Mac, or any support (Sorry Mac users).

Bug Fixes

• Fixed game-breaking bug that prevented you from playing multiple times in a single session.
• Modified enemy pathfinding to prevent collisions with walls from happening as often.
