Fix LoggingManager after event change.

Fix layout issue from MigLayout update

The mainframe just laid out really badly, splitpane didn't grow, the
statusbar was underneath things.

Stop using Window and InputWindow.

These interfaces are basically pointless.

Remove some uses of Window.

Window only has a getContainer() method, so we may as well just
pass a WindowModel around instead.

Make the WebSocketController subscribe to events.

Web UI work.

- Pass in ID
- Don't burst the full backbuffer

Spark doesn't work with recent versions, old versions of Jetty
have nasty bugs, and spark doesn't really give us much benefit.

Allow anything in a sub-directory, such as services. This greatly
simplifies embedding complex software such as Jetty.

Add a 'provided' scope.

This prevents DMDirc's transitive dependencies from being bundled
in plugins. e.g. DMDirc includes SLF4J, so any plugin that depends
on it (or depends on another project that depends on SLF4J) should
not include it in the plugin jar to avoid having duplicate classes
from different class loaders.

Restructure to standard maven/gradle layout.

This didn't need changing in the first place :(

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.

Change dependencies after parser group change.

DMDirc/Parser#23

Update dependencies.

Add ability to hide nick change events in the jpq plugin.

Closes #428

Hide away label on server reconnect.

Close #426

Random unhandled exceptions are our fault.

Closes #681

Fix logging plugin's handling of self query events

Log entries should always go to the file corresponding
to the Query, rather than to the user that happened
to send the message.

Closes #430

Fix HistoryWindowTest.

Fix ConnectionHandler check.

Comparing an Optional to a Connection doesn't really work.

Fix a couple of tests.

Add source checks for eventbus handlers.

In preparation for child eventbusses being removed, anything
trying to subscribe to specific windows now needs an explicit
check.

In the process, fixed two issues:

- channel who plugin was sending way too many requests - each
  connection was querying every channel in the client. i.e.,
  with 5 servers open there'd be 5 WHOs per channel...

- ServerFrame stops itself listening when *any* frame is closed.
  So closing a channel window then reconnecting wouldn't offer
  an SSL dialog, because it's already unbound the listener.

Issue DMDirc/DMDirc#662

Random test tidying.

Support for core changes.

Fix date format when showing errors.

Closes DMDirc/DMDirc#661

Handle core date API changes.
