Now using ints to store IDs of Room objects. This means they can be identified without having to make multiple copies of themselves.

Retouched the exits array to take ints instead of objects. These ints point to Room object IDs..

Room can now be written to file properly, in a format that will be easy to read in.

Add New Room frame can now be closed without exiting the app entirely.

Added and retouched most of the Room.java class. Changed how it stores exits, how it writes to file and what data it needs to be created.
