Try to keep track of channel keys (Close Issue #108)

 - Parses outgoing JOINs to try and guess keys before we get the MODE reply.
   - Parsing algorithm based on Quakenet/Hybrid handling of keys.
     - Keys are swallowed from the key-list for EVERY channel that is
       to join, even if it is not needed, so you would need to use
       "JOIN #Foo,#Bar,#Baz Foo,,Baz" to join keyed channels #Foo and #Baz.
 - Key changes by mode +k and -k will be tracked.
 - Ignores attempts to set the key as "*" if we know a "better" key.
   - Side effect: If the key is actually set to "*" we can only learn it if that
     is what we join with, or it gets changed to that from no-key.

Some additional WHOIS bits that were missed.

Tidy up a few asserts.

Migrate parser events to use new date APIs.

Java 8 introduces a sane API for dates; to store datettimes
we should now be using LocalDateTime.

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.
