Description

Read a chosen membership expiration from the user_search.html invite form. Also display expiration in the group view.

Change the form to use a date, not a datetime -- seems silly to chose the minute of expiration.

Some light JS was necessary to enforce minimum today's date, and maximum some way into the future: currently 5 years. Can maybe be a setting passed into the template?

Fix a double quite typo: <form action="{% url 'imperial_coldfront_plugin:send_group_invite' %}" method="post"">.

Fixes #84
