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.

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

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

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 #82.

Just does ircu stuff for now.

These need to be rewritten as proper unit tests.

Remove all tests that depend on TestParser - they're rubbish and
need to be completely rewritten to be proper unit tests.

Seems a bit odd for each implementation to define a method that
*always* returns a static String[] when we can just pass that
up to the base class.
