migrate tags from charfiled to new pg array field.

We added 4 migrations. The first one adds a new field tags_arr which is a pg array field.
The seconds one is a data migration which takes all tags from the previous
tags charfield, parses it and adds it to the new tags_arr field.
The Third one removes the old tags field. And the last, fourth one,
renames tags_arr to tags.

small refactor of members app
forgot to commit event/forms
fixed a few places in templates where tags where not being displayed correctly
add ability to search over tags
refactored members login to use form and not raw post data
more members app refactorings

using some of the django admin UserAdmin mechanisms for handling
member user creation and change. as with contrib.user we know only
create a user with username and password combo. Then we are redirected to the
change view where we fill out the rest of the info. The password is not displayed
in the change view but we utilize a password change form from contrib.user.
We use md5 for hashing password and secret_key for salting. it's not perfect
but it's better than before.

Also, we removed the contact_type table as there is not need for it.
Insted we added 3 Types to the Contact model: email, phone, cell.
A data migration that migrates old data from the contact_type table
to the new charfile is also in place.
