Actually set the event bus error handler...

Update to MBassador 1.2.4.

This release contains some performance improvements compared
to the version we were using.

Error handlers are now passed in at construction time, so
there was a small bit of refactoring required.

Set ADDRESS and REAL_NAME property after whois.

Having two separate events means the ordering isn't guaranteed.
Handle everything for 311 numerics in one handler.

Don't allow resetting state whilst socketClose events are still occuring

Always provide a 'kicker' client.

When we moved to events, we stopped passing null in place of clients.
Instead, fake clients should be used. Apparently ProcessKick wasn't
properly updated.

Fixes issue #100

Modes should default to "" not null

Bump gradle version.

Stop circle build failing.

Unshallow the git repository if necessary, and fetch tags.

Both of these things are useful for versioning.

Make method names in ProcessorsModule unique.

Issue DMDirc/DMDirc#601

Make the Simple*Handlers actually do stuff.

Don't double format debug info.

Delete CallbackNotFoundException.

Build process tidying.

- Execute coveralls as part of tests, not afterwards
- Update script to plugins version to allow for files that don't exist
- Use jcenter for DMDirc plugin, to stop idea complaining

Narrow some scopes for some variables.

Create a TrustingTrustManager instead of an AIC.

Ensure client modes are non-null.

Fixes #82.

Use nifty separate handlers.

Add JUEL.

Add support for away messages in whois replies.

Add a method to get all info in UserInfoEvent.

Add a whois reponse handler.

Just does ircu stuff for now.

Add a couple more enum entries.

Add the start of a UserInfoEvent.

Use fake clients in a couple of places.
