Programmical plugin registration

[XakepSDK]

Add a way to register plugin through API. I need this for bungee api proxying.

I'm unlikely to grant this request, for a few major reasons:

• Velocity is not intended to provide full compatibility for the BungeeCord API (the goal is approximate parity). It has a very different design philosophy.
• Velocity intentionally does not support dynamic plugin enabling and disabling. This approach has proven to be extremely prone to breakage (just look at everyone who admonishes the use of /reload on Bukkit). This is similar to what Sponge does and it's an approach I consider to be better overall.

In conclusion, you'd be better off keeping the Velocity and "fake Bungee" worlds separate, if you really wanted to undertake this project.

Even better, why not write some native Velocity plugins? We've already got a few major plugins ported to Velocity (ServerListPlus, LuckPerms, and soon NuVotifier), and these plugins help form the core of most peoples' servers. We could use a more complete suite. Shimming the BungeeCord API doesn't help us generate our own plugin ecosystem (I make an exception for the widely-used BungeeCord plugin messaging API).
