Add support for testing other browsers via selenium.

This allows for testing in Chrome as well as the default Firefox
(not that any of the tests get anywhere near passing), which should
make it easier to get things moving (or to add IE testing at some
point).

Merge branch 'master' into selenium
Bump to the latest version of selenium

This supports dev instances by default.

Remove redundant line, bump browser headings down a level.

These aren't really top level headings.

Add support and examples for using HTMLUnit.

This is a headless browser which provides flexibility, though doesn't
let the developer see visually what's happening.

Tidy imports per PEP 8.

Fix title and login selenium tests, part fix registration.

This updates the tests for the current UI version, and adds some
helper methods for getting elements & asserting their display state.
The registration test mostly works, but doesn't seem to show the
div properly for reasons unknown (it works manually).

Update testing of user display, add test for the self-link.

This doesn't yet cover actual user editing, or any specifics, just
that the right box is shown, with the right username.

In order to do this, add helper methods which wait for a given element
to be shown, based around a helper method which waits for a predicate
or a timeout.

Correct outdated local.py name in readme.

Correct name of the chrome browser file.

Change default Chrome handling to go via the server, update readme.

This modifies the chrome browser example to allow either direct
control of the driver, which it turns out is slow, or access via the
server which is faster. Also update the readme to reflect this, and
tidy it up in the process now that we (almost) always need the server.

Improve assertion failure message.

Remove user that shouldn't be present.

Add a test for a student using the self-edit link in the top right.

This is about as close to the case of a user not being in a college
as we can get for the moment.

Merge and update the registration display and function tests.

There seems little point having one test which is going to effectively
duplicate the first portion of another test, as it may as well just
be one test. Ensure that the created user is not present in either
LDAP or sqlite either before or after the test runs so that it
should always work. Include handling of the feedback display so that
developers can see (via assertions) what error messages the user
would see.

Change-Id: I0d1159b0583ccf348e7f73d60e4eef32cd41b556
Add helper to get the informational feedback messages.

Change-Id: Ia5ee1a59c59ececb3b3d04e81a898a6852374e33
Rewrite & simplify the user editing test.

We no longer edit the password as it's simpler to only have to reset
the email address (since this doesn't actually get changed in LDAP).
Check that the updated data is correctly displayed per the new layouts.
