Merge remote-tracking branch 'upstream/master'
Now only display the survey total chart on the main page.
Remove superfluous label.
Move the directives.js file to the correct place. Gets rid of the 'no
module named askApp' error.
Some respondent detail page tweaks.

- Hides the back button if we don't know where to go back to (someone
  bookmarked the page without the base64 part, maybe?)
- Adds some 'Set Status:' helper text to make it clear what the drop
  down is doing
- Changed the header sizes
Merge remote-tracking branch 'upstream/master' into feature/Survey_stats_page
Fixed typo on detail page. Fixed bug where a PATCH would happen on
detail page load.
Actually fixed the PATCH bug this time.
You can now edit the 'review_comment' field on respondents via the
detail page.

I went with a 'timeout and then save' model for the updating.
Waiting on the ability to get the next survey.
Actually saves when you hit the button now.
Added survey-stats page.
Fixes #159.
Fixes #158.
Added print buttons to both the survey stats and overview pages. Made
the print button a directive because you can't use window in ng-click.
