Updated requirements to our fork of django-haystack
Initial work on the ModelForms for events
Customise django forms
Template for create event
Added bootstrap form
Save event on POST
POST to correct path
Added logging for API failure
Set slug on save override
Added separate form to enable the event groups

Can reduce the 3 event group forms to 1 I think
Single form to create an event group
Move to one EventGroupForm
Validate between the Select and create new EventGroup

Added simple booleans to manage this selection for now
Added missing import
Attach EventGroup to Event if we have one
booleans for now...
