This allows running DMDirc from IDEA, which seems useful.

Running a normal build just replaces the file in the build output.

At present anything requesting the global config has to depend on
ClientModule, which won't necessarily be exposed through the API.

Move @GlobalConfig, @AddonConfig and @UserConfig to top level
classes in API, and provide both versions of them for now.

Update dependencies

Mockito now errors if a mock is unnecessary, plus a few other minor
API changes.

Update gradle to 3.1.

Move IRC control codes to their own class.

Some other minor tidying to Styliser.

Extract interfaces for BackBuffer and IRCDocument.

More interface/API work.

Rename the private implementation to ConfigBinderImpl, and
make ConfigBinder itself an interface.

ConfigProviderListeners aren't public.

Remove ConfigTarget from interfaces.

This shouldn't be exposed. Internal classes switch to using
the full class rather than the interface, so they can carry
on accessing the removed methods.

Use EventBus interface.

This is just an IntelliJ refactor, using EventBus in place of
DMDircMBassador whenever possible.

Add an interface for the event bus.

Our API shouldn't depend on MBassador. Extract a simple interface
to break the dependency.

Start work on an API project

This is for the interfaces/trivial implementation classes that
DMDirc plugins can interact with. Eventually plugins will build
against the API instead of the DMDirc client itself, which will
allow for remote/detachable clients (amongst other things).

Replace Query with PrivateChat in Connection.

Use PrivateChat for events, not Query.

Issue #76

Don't fiddle with ports before passing them to the parser.

If the user doesn't specify a port, allow the parser implementation
to figure it out for itself. This allows for things like SRV lookups,
or different default ports per protocol.

Remove Window and InputWindow.

Make link events use WindowModel.

Add an event for frame opened.

Avoid raising events before a frame has an ID.

For some reason this was only exposed through the WindowManager
listeners.

Make LogUtils try some more ctors.

NoClassDefFoundError only takes a message (no source). Try
throwable-only and message-only ctors in addition to the
two-arg ctors.

Fix stupid broken error message.

Tidy up nick change handling.

It doesn't make sense to have a public method in Connection to
muddle around with how queries are tracked, nor for queries to
tell servers when they change (creating a dependency loop).

Instead, have the ServerEventHandler tell Server.
