Make May AI Data-type month for OS 4

Hi guys,

Sorry... late catching up with this thread... Cool Stuff!

regarding datatypes vs. HTML for the MarkDown data - It seems
like making a datatype would efficiently allow for any dev to
incorporate that in a proper program to see the resuls while
still maybe being able to edit the file on the fly. Of course
that gets into the question of file locking, etc etc.

Extending existing datatypes or creating other ones sounds
great!

These were always intended to be modular - whether done by or
with a bot or by craftsmanship.

Have at it!

Thanks guys!
