This allows the logic to be expressed more nicely and tested
independently of the handlers. It also paves the way for a
bit of refactoring to reduce the number of random things
that need to be comparable...

Use Java8 date types for parser queue items. Fix the time check in
QueueHandler to check if the item has been queued for longer than
10 seconds, rather than if the item was created within 10 seconds
of the epoch.

This gives us access to MessageTags (#19) and pre-tokenised lines in DataIn rather than everything neededing to tokenise themselves.

There are probably a few other events we want to expose messagetags on that we still don't.

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 issue #100

Issue DMDirc/DMDirc#601

Fixes #82.

Just does ircu stuff for now.

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