Made second age strategy same as first. Added a default card if no other options were available.

Create generalfunctions.py

Need this file in this folder because person.Person calls it.
Changed Random to RandomPlayer. Fixed mistype.
Changed strategies to strategy. This allowed me to use the folder with the strategies in it instead of having them all in one file. Related to issue #3.
Made import adjustments to person.py because random is not used in it.

Deleted generalfunction.py and strategies.py in accordance with issue #3. These files were actually moved and split up into the folder strategy.
This closes #4. Needed to rename all the files so the class name and file name would be the same.
You can now vary by difficulty level. Closes #5.
Minor aesthetic changes made in the code.
Finished MaterialPlayer this resolves #1. I choose to put this in difficulty 2 for right now.
