Adding support for creating embedded and worker thread plugins
Resolved conflicts in pluginLoader.js
Set linters to be created in worker threads again
Refactored plugins to have a dev directory and a default directory to allow for easier plugin development.  Also added a disabled directory to hold plugins we don't want to check in and don't want to load.
