Update to latest fabric scripts from model_django_project
Prevent editor being emailed when editing feedback

To do this we've added an editor field to the Feedback model so the
post save signal handler can exclude them from notifications.
Removed global functions from models.py. Tidied up get_feedback_statistics
and reduced queries made in template code by putting query outside for
loop.
Merge branch 'develop' of github.com:aptivate/econsensus into develop
edit feedback notifications are now not sent to the author of the edit
So if the original author edits their own feedback they won't receive
a notification. The tests are now tweeked so different Users make
the edits, which still prompts a notification.
Added signup url to login page.
Fixed bug in account activation email. In django future urls, url name are quoted, variables are not.
Admin interface for django-organizations uses django-guardian
protection.
Created data migration to give all existing Users of an
Organization the edit_decisions_feedback role.
Getting permission denied for file creation /var/log/httpd/econsensus.log
So move to /tmp/ until fix is sourted out.
publicweb migration 0032 requires that guardian is installed and synced.
Therefore guardian has to appear in installed apps before publicweb.
Reapply ".summary-header" context to ".feedback" selector that gives
fixed width of 8em to feedback column of decision list tables, otherwise
width also gets applied to form for creating new feedback!
Prevent adding of new feedback using feedback rating count bars when
current user does not have editor permission (with javascript both
disabled and enabled). This solution avoids duplication of template
markup *and* minimises "if" tests in the template.
Allow longer values for feedback type counts and made lozenge background
look prettier for various length values.
Added label for Last Modified timestamp for Proposals in row-by-row responsive
layouts.
Users can now create their own organizations.
Uses the same form as for login so renamed 'login-form'
to 'short-form'
Tidied up indenting.
Screen width <= 640: Proposal/Decision/Archive list screens: remove "Excerpt" label and make excerpt span entire width.
Editing email subject lines.
Removed site, added 'EC#', consistent User name use, 'replied' for
django-comments.
Tweaks to Organization create template to make it more user friendly.
