Implement new RobotContainer.java and Constants.java Classes

- OI.java has been deprecated and replaced with RobotContainer.java
- RobotMap.java has been deprecated and replaced with Constants.java
- Changes have been made to use the new classes without errors; some of these changes will be changed in the future
