Player class made into a singleton

Created a private static instance variable of the player, and also
created instance variables of Ship and Planet (aka the location of the
player). Added needed getters and setters.
Resolving personal file screwup.

My files were weirdly placed after trying to get the program to work, so
I'm going to commit to put my files in the right place. If something
happens, let me know.
