Testing getting exif data
Merge branch 'develop' into exif-data

Conflicts:
	model.py
Read and store exif data when upload photo

Exif data is displayed on the photo's page in a
bootstrap accordion. Only photos uploaded after this
update will display exif data. Need to manually update
previously uploaded photos.
Small tweaks
New scoring method and checks

Can score between 0 and 10. Added javascript to
check the user has submitted scores for all
photos.
Competition comment link

Change the location of the link to the photo page with comments. It
is now part of the results table. The text also shows the number of
comments for each photo.
Database help

When I want to make many changes to the data on the server, I'll
use the files in the help dirs.
Minor fix
Merge branch 'develop'

Conflicts:
	app.yaml
Create button and popover exif data

Hidden button on photo, when mouseover photo, the button
fades in and when clicked it displays a popover of the
photo's exif data.
