plugin.yml is not included in build jar after packaging

[RepComm]

Spigot fails to load the plugin when:

1. cloning repo
2. running mvn package
3. copying output jar to plugins directory
4. running the server

Going to try and patch this and pull request

Latest release does not include plugin.yml and causes error:

Travis seems to be building release jar incorrectly

[grakkit]

Travis deployment has been disabled in favor of manual deployment. This will prevent any faulty automated releases.
