Some things are incredibly broken. Basically rewriting a lot of
the code to work asynchronously. SQL was rewritten for smaller functions,
scanning is now asynchronous (should be anyways). Compacted Slackbot
a little bit, also changes icon based on number of servers down
(once I've fixed all the other bugs :D).

Decided to nix async (for now) because I have no clue how to properly implement it.
Instead decided to use threading, which should work just fine (benchmarks TBD).
Also fixed SQL.py not commiting to the database (derp).
