added Copy/Paste plugins so that you can copy/paste between different servers.
moved runCommand up into ScalaPlugin
made a real Point class instead of Tuples because of some weird implicit for x.
some other minor refactorings

added spawn to ScalaEnrichment
added configs to ScalaPlugin (which generates config.yml)
