Update to the math tool to make it more flexible, return better error messages, and generate fewer problems.

Moved the ASCII-Picker to the internal folder, so it wouldn't be in the user's folder and get deleted so easily.
Added a MathEval folder into the internal folder, so that users could store custom quick-add code and set user variables for the math tool.
