refactor entire kane-quneo-mixxx codebase

[wolfbiter]

this file could be a fraction of the current length if i were to rewrite everything (simply because now i have so much better of an idea what to do. standard coding thing). plus, the script would run faster because a lot of the logic is redundant/slow...

however i am going to postpone this until either it's actually a functional necessity or i have a lot of spare time and motivation.

after spending a ton of time on static code implementing what should have been the relatively simple #94, it's clear to me no major changes should happen until this issue is fixed. the code is far too spaghetti, and it's in my best interest to leave this project be rather than try to expand on it - that is, of course, unless the whole codebase is refactored. who knows - maybe mixxx will come out with enough new features to warrant that...

fixing this issue will certainly be the 2.0 release
