remove EQ presidency type from the eq_presidency table

[apippin]

We no longer need to reference a special entry in the eq_presidency table with the eq_ppi and eq_visit table changes (issue #6 and issue #7).

• Remove the eqpres field from the eq_presidency table
• Modify the directions on the admin page to remove references to it
• Change the email tool to understand how to send an email to the EQ presidency. Query the eq_presidency table, and collect the email addresses for each presidency member when sending email to the presidency.
• The scheduling tool will need to special case the creation of the EQ presidency visit table.

I think these issues have been resolved in version 1.0.0. Owen, can you comment on that?

I think you're right. Issue #4 captures the extra stuff I'd like to do around this. So, I'll close this out.
