Campsite + Mailfloss Integration

Keep Campsite and Mailfloss aligned: use one app's communication actions to perform the other's.

Example: use Campsite's "Create a DM Message" action to perform Mailfloss's "Cancel a Batch Task" action. Campsite has 12 actions (including Create a DM Message, Create a Message, and Create a Post); Mailfloss has 6 actions (including Cancel a Batch Task, Get a Batch Verification Task Status, and List Batch Verification Results).
