add findup-sync module
add delete command to config
require a core-object with an extend method to extend off of the Command object properly. thanks stefanpenner/ember-cli
add project model to use when inside of a project
change command to have a parseOptions and validateOptions method instead of a single validateArguments. remove this.args from it as it was just duplication
verify a callback exists before trying to call it in run-command
change link-environment to take a project as an option since it is run from within a project
