moved datepicker from base to create_event and tavern_update_event
We don't need both bootstrap.css as well as bootstrap.min.css. One should be enough
A jquery file is already inherited from base.html. So no need for it in child template
bootstrap-datepicker.js should not be part of base.html. This js in only needed on create/update event page.
Merge pull request #15 from agiliq/datepicker
