Stop swimming against the tide and accept what most of the rest of
the world does.

While it adds an annoying depth to the actual source code, it makes
the root directory nicer (no more 'test-res' dirs), means we don't
have to override the gradle config, and makes it nicer to work in
IDEA 2016.1.

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.

Assert that things aren't randomly null. This will make it easier
to fix than trying to hunt down obscure errors in the client caused
by nulls here.

Remove CallbackManager hacks.

We now pass parser/date in properly, no need to drop these and
re-add them.

Remove "non-critical" callbacks - if callers want to ignore the
exception they can just try/catch it.

Make addCallbackType private, and remove the unused delCallbackType
method.

All callbacks are now done through getCallback, which offers
type safety (gasp!) and is potentially extensible in the future
(wow!).

This means that nothing can depend on callbacks existing, so
there are two functional changes:

 - the parser will no longer disconnect automatically on failed
   pings; users have to listen for the event and handle it
   themselves;

 - the parser will no longer attempt to automatically use alt
   nicknames or create new nicknames on connection; users have to
   listen for the event and implement the logic themselves

Both of these were really weird anyway, as adding a listener (even
for debugging purposes) disabled the built-in behaviour.

Previously it added an object as a callback target even if it didn't implement the callback handler, this was pointless and stupid, now it checks.
