Refactor with a pure Python spell checker

This is a major re-write of the code.  It now uses pyspellchecker,
a pure Python package, replacing pyenchant, which required the C
enchant library underneath.

Also code has been re-organized to make seperate functions into
smaller, more manageable parts and to adhere to Pylint's coding standards.
