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.
OutputQueue is now abstract, and the different queue methods
are subclasses.
This allows the same flexibility as before (subclasses can change
the type of items they add, implement their own throttling logic,
and say how the queue is ordered).
Organising it this way makes the package a lot easier to understand
as there's no longer a messy separation of concerns between
OutputQueue and QueueHandler (e.g. the output stream is no longer
in two places with two send methods, all of the definitions
relating to how the queue works are in one place, etc).
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...
OutputHandlers are now incharge of creating QueueItems and comparing them.
Parser now allows for replacing the OutputQueue entirely
Default OutputQueue allows replacing of the OutputHandler (by giving it a new QueueFactory that outputs the alternative QueueHandler)
Sending PING is now High Priority
QueueItems now sort by a unique itemNumber not time, as priority queue doesn't guarentee order for itesm of teh same priority created at the same time
Add a rate-limited OutputQueue
