Updated Take Photo page to include verification requirements

The version of django-debug-toolbar-mongo we have installed does
not support our version of Django Debug Toolbar. The author did
accept a patch that supports the latest version, but has not
published it to PyPI. This just grabs it from the github commit
instead.

Note: This will not uninstall your old version. If the MongoDB info
is not showing up for you in DJDT, try manually uninstalling with:

  pip uninstall django-debug-toolbar-mongo

Running "paver lms" after that should install the right thing.

As part of the unification of verify later/now, the take photo page needs to list the verification requirements.

Clytwynec/unique dirs for test results

Paver: Ability to run only servers or only tests

Enable unit preview by default.

Bok-choy on chrome: fix sequence for adding user to team.

TE-849

This passes fine in firefox; however in chrome, the click is occurring before
the page is ready; and then the click itself is not specific enough. Also
refactored the add button method so it more-clearly returns the expected
end-state.

This would allow a user to set up and run servers, with an open prompt for killing
them. Likewise a user could open a different terminal session and run tests only.

How-to:
* At a terminal/ssh session, start bok-choy servers with
    `paver test_bokchoy --serversonly`
    (or, if you've already run collectstatic on your system:
    `paver test_bokchoy --serversonly --fasttest`)
* When the above is running, you can now open a separate terminal/ssh session
and run:
    `paver test_bokchoy -t my_tests --testsonly`

Keep in mind, the 'testsonly' flag does no setup. There is some minimal teardown; however,
such as clearing mongo and flushing the lms database. (Some tests have non-unique identifiers
and could not be run more than once.)
