make automated tests

before sweeping refactors have to happen, start off by bodging this into the system:
https://github.com/DXsmiley/dismock

after that is mostly working, the separation of logic and discord function calls should be separated. Thus, tests can be made that don't rely at all on the discord API

It's probably a smarter idea to clean up the code, then decide if more 3rd-party libraries/system are necessary. dismock might end up being unnecessary, which hopefully would mean less brittle code.
