Implementing a plugin updater + dependency management + semantic versioning

[sphinxc0re]

Hello

Since our WorldEdit clone now has an automatic updater I once again thought about implementing one into the server, that supports updating plugins by using semantic versioning (http://semver.org/)

I'm imagining a file called plugins.txt

Code:

Core@8.0.1
WorldEdit@2.1.0
Essentials@3.1.2
...

Plugins would have to use semantic versioning in their info.lua
