Generate tutorable moves for shared use by C and Python

[lhearachel]

Pull request #191 introduces a Python utility for interpreting tutorable moves from individual species' data files and building the table for all species to be included in the ROM. However, it makes use of a hard-coded copy of what moves are tutorable.

We should explore generating the table used by both the ROM and by the Python utility that defines what moves are tutorable (as well as what the cost of a tutor is and which location's tutor can teach the move).
