Revert "Reverted version numbers after merging bugfix from branch dev"

This reverts commit f027cf6e76c3b081a10b72b1d8c4fc4747615b8d.
Began overhaul of remote admin server protocol

HandleRemoteClientTask currently undergoing major rewrite
Updated version number on EverCoreUtils dependency
Trying to do things with players who have never played on the server before will now correctly error out.
Added a big ASCII banner that prints when the plugin is started without WorldGuard.

Hopefully this cuts down on the number of people who join my IRC channel asking why the plugin won't load...
Moved dependencies to XPE's repo
Trying to add a duplicate plot now correctly reports failure.
Fixed regression in checking if the player is a valid player- forgot a ! in front of the conditional...
Added license file to root of project, for github
Serverside auth code almost done for MCTRA.

Still need to make the server prove its identity to the client. I'm also just going to have to bite the bullet and disconnect post-auth, because I can't re-use those streams when an Object*Stream pair has already been used on them.
Fixed issue from last commit, can now successfully open secured streams to clients
Cleaned up RemoteConnectionServer to expose a bit of public API rather than have it pass internals to HandleRemoteClientTask
Added OverView packet
Removing all remote admin-related code to move into own branch
When a sign is created for a plot, it will now face in the opposite direction of the player.

Fixes issue 19 (https://github.com/jmhertlein/MCTowns/issues/19)
Added relocations to pom.xml for shaded EverCoreUtils
Corrected deployment location, added EBCF as dependency
Added resource upgrade from 2.2.0 to 2.3.0
Updated version numbers for 2.3.0-LTS release
Removed EBCF from dependencies
