Forge should support dynamic loading of plugin library dependencies

Right now, Forge extensions must use the maven shade-plugin to package referenced dependencies of plugins. It would greatly enhance developer experience if referenced plugins or libraries could be dynamically loaded from the local maven repository, even if built with Git.
