(Same PR stuff as Py3 but Py2 friendly)

This PR does the following

• Makes an attempt to improve the poem game from Dan's code using Screens than ui.X functions
• Makes an attempt to improve the poem game from Dan's python code using Classes and inheritance.
• Adds the ability to add more characters easily using the Chibi class (or ChibiTrans if you don't need points).

This still requires some code editing for screens and points however. See the new guide in Documentation for more information.

• More efficient poem word storing via dictionaries.
