Make certain Theme variables private. Fix dot notation for relative import
3.0.0
Removed dependency on PIL, since adding an image does not really fall under the category of "making themes EZ" Speaking of themes, did a little refactoring to follow better patterns/cohesion for theme classes. Themes now belong to a Theme class, so set_theme(Theme.Dark) is now possible.
2.1.6
Fix an issue in which distutils was excluding setup.py in the MANIFEST file because I had named it Setup.py. This was previously not an issue.
