Try out Sentry for error handling
Persist sections added in the Class Overview on the server

Doesn't yet persist section assignments.
RSVPs belong to 'sections' for purposes of class sorting

RSVP section assignment is persisted when draggy-dropping
in the Class Overview page.

Fixed glaring security hole where any logged-in user could
update any RSVP.
Use root key of 'attendee' when updating section_id for rsvps

Add rudimentary "oh no!" error handling to section organizer requests
First pass at sorting hat section arrange algorithm
Fix section arranger crash from 'count' coming back as a string
Volunteer count ignores no-shows when event is no longer upcoming

Student list now greys out no-shows like the volunteers one did
'Volunteer Email' page is now a generic 'Email Attendees' page

Email page allows ad-hoc emailing of attendees

Email page shows # of people to be emailed through some
relatively poorly tested Coffeescript.
Adding 'checkiner' role for volunteers that are allowed to check people in but not be an organizer

Add attr_accessability to rsvp

Redesign organizer dashboard a bit
Section organizer: group sections by average student level

Use level colors from RSVP (blue-green-gold-orange-purple) instead of other random colors
Display non-checked in users as greyed out on class sorter
Add button to arrange only checked-in people
Fix unsorted column to left for checkins only sorting
Sec organizer: Backfill jasmine tests for attachPoint on section view
Consolidate "validate_organizer!" and "require_organizer"

Now there is only validate_organizer!, which lives in ApplicationController.
Halfhearted attempt to make navbar look better at small page widths
corrected broken Heroku Toolbelt link
Merge pull request #183 from unicornzero/master

Corrected broken Heroku Toolbelt link in the readme
Remove modernizr (was only used for native datepicker detection)

Upgrade jQuery (1.10) and Handlebars (1.0)
Remove DatabaseCleaner in favor of single-threaded transaction specs

Use warden's login_as in feature specs instead of always logging in via
the form.

This shaves about ~25 seconds off the total test run speed
 * 20 from transactional fixtures
 * 5 from login_as
