Never ignore your linter.

Update slack library to latest master.

Switch to SlackAPI fork to workaround nlopes/slack#604.

Fixes #60

Update deps to pull in bugfixes. (#55)

Add sections on configuring and debugging.

Fix potential usage of uninitialized reverse mappings.

If we receive a `user_change` event before `regenerateReverseMappings` is called at the end of `bootstrapMappings`, we could potentially attempt to modify these `nil` maps.

Since I can't remember any good reasons why these shouldn't be initialized to empty maps (and all the code seems to assume these will be non-nil anyway), initialize these to empty maps on SlackClient creation.
