New branch created after experiencing errors with master-branch merging.
Stopped by Prof. Ames' office and concluded it would be best to make a
new branch altogether and update the files manually to match the old
branch.  In this vein, 'items' and 'inventory' branches updated to match
old branch.
Updated PlayerMotion class to support proper functioning of the copied
'items' and 'inventory' files (flying, speed counters, distance
counters)
