Export actions so we can use our own action bar

I guess this is it. Have I missed something because I wanted to have my own actionbar that I would be able to link to the pell content.

No file, test, or entry point is named. Start by locating how Pell defines and renders its actions and how consumers access the editor content; clarify the public API needed for an external action bar before making changes. Done means a consumer can connect a custom action bar to Pell content, with coverage for the exposed behavior.
