Replacing redundant Waterloo API logic in relation to getting term names from term codes

[sai3000pro]

This issue is an extension off of #316 - a function called convertTermCodeToTermName was implemented, but there is now a lot of redundant code with the Waterloo API logic that should be removed (since it doesn't work).

I guess a question I have now is what would be considered redundant? Is everything involving the Waterloo API broken? For example, validateTerm goes through the file that was returned by getTermNames, overwriteTermFiles overwrites these names in case validateTerm fails...

I can test these out later this week but wanted to ask in case anyone knew!
