Addressed on branch https://github.com/bwaldon/activedop/tree/edit-fromgit, which introduces a reload_grammar endpoint. Roadmap for addressing on the AWS branch:

• Merge remote app support  #132 into nschneid/master
• Merge nschneid/master into bwaldon/edit-fromgit
• Merge bwaldon/edit-fromgit into bwaldon/mb (the branch from which AWS Docker app is created)
• Push Docker image of bwaldon/mb to AWS
