Features/v5/event results (#2706)

* Begin events rewrite using Guava EventBus:
- moved events to within core
- removed BukkitEventUtil
- EventUtil in core is now the implementation
- Refactor any event calls

TODO:
- Test :)
- Implement changes to PlotSquared's own listeners
- Other

* Correct code style for annotations and refactor EventUtil to EventDispatcher

* Make getEventResultRaw default method and remove empty PlotEventListener file

* not raw map

* Remove PlotPlusListener

* Add listener registration to PlotAPI. Add documentation and refactor Result enum

* Add reason for the Event Result. Change how the claim event is called
TODO: better auto event somehow. Possible re-write of auto required..?

* Implement changes to events properly
Add PlayerAutoPlotEvent
Add PlotDoneEvent
Add schematic variable to Claim event and allow it to be changed
Add reason for plot unlink to unlink event
Add pattern to component set event and allow it to be changed
Allow component of component set event to be changed
Add player to plot merge event

* Fix compile

* Correct formating

* Various cleanup
 - Correct formatting in places
 - Add feedback to Desc command cancellation
 - Correct use of flag API
 - Add FlagRemove event to flagcommand where required

* Replace reason with caption

* Switch colours in Event Deny caption
