added Save class

can't load anything but seem to be able to save name.
Implemented save and load (almost)

Saving and loading works using a hybrid of text file/serializable
methods. Current SolarSystem and Player are saved and loaded from a text
file, the Player's Ship is saved and loaded from a bin file.

The only thing missing is to save/load the Universe which I should
hopefully have finished tonight.
Fully implemented save/load

Saving and loading now works for everything necessary. It's a
little.....sloppy, but it works! For now that's all that matters.

I'll write some comments tomorrow to explain some of the non-intuitive
stuff.
Removed some extraneous files
Cleaned up the code

Removed pointless save/load binary methods and unused imports
Merged Save and master branches
