Have an explicit list of event `types`

[karthikb351]

Currently, HasGeek does a wide variety of events - Conference, Workshops, Meetups, etc.

We need to flag every event we do as a specific type, this will help keep events of the same type consistent while still allow each type to have its own special requirements.

Workshops use instructor while conferences generally use speaker, and meetups may use register or rsvp instead of tickets, etc.

We need an exhaustive list of event types.

Here is my list of event types that we do, including digital ones:

conference talk crisp talk panel session off-the-record unconference birds-of-feather demonstration discussion group miniconference workshop (i.e one-time event or short series) class (i.e. ongoing series) bootcamp hackathon open house meetup lecture food court livestream podcast webinar video (on HG.tv)

And in a different set of tags, our events are co-sponsored, sponsored, private, corporate or public.
