Fixed errors in making the keybinding replaceable.

Browse Source 
- Changed KeyFactory to not be a singleton
- Simplified keyBindings initializer
- Modified and simplified keyListener
- Added method to copy existing keyState
- Changed button events
- Changed to newer lambda functions
- Modified updateKey method
- Left option for multiple keys bound to one command
- Updated and wrote new JavaDoc
