Small code refactor and filter

David, Ryan, and team,

Firstly great plugin. I have one developer driven feature request that should be simple to deliver.

Basically that you separate out the static function create in class-micropub-endpoint.php, into two seprarte functions.

The first should prepare all the arguments and the sec ond should actually insert the data into the database. The second function should then have an additional filter right before wp_insert_post to allow for the indeiweb content to be inserted into another table, rather than wp_posts.

My use case being that I want to integrate buddypress with micropub, and as such I want to map some of the indeweb content types into buddypress type activities which involves inserting them into a different table.
