Add note about needing to revert onboard_types post-install

Addresses #3484
Member content type instead of Person

In the check-in on 2013-12-05, Nina and Michael thought the
language of "Person" was confusing, not used by project stakeholders
and inconsistent with the language in the user stories.

* Remove the ``Person`` content type and add a ``Member`` content type with
  the same fields.
* Change the reference on the ``Board Term`` content type to be named ``member``  and reference a ``Member`` node.
* Remove the ugly "TODO" message for the label of the ``title`` field of
  "Board Term".
* Updated text and path in custom menu to reflect "Member" and
  "node/add/member"
* Update tests to reflect these changes.

Addresses #3483
Correctly handle dates in feature definition

DrupalExtension handles entity date fields with start and end dates
by specifying them as comma-separated values.  Update the tests to
use this syntax.

Also fix a typo where "edit" was used instead of "delete".
