Adds a slew of new tests

This test needed a bit more coverage to test the various link, images,
and email form at the bottom.

I replaced the existing functions to gather links/images with
explicitly declared elements and locators. I think this is probably a
better approach since we want to test against what we expect to be
there, not what is actually on the page.

I added a function that allows you to select options in a select drop
down menu. since it takes a few lines to accomplish that.

I updated the `get_response_code` function so that it returns a timeout
http response. I noticed that http://getmockery.com/, one of the links
on the page, never loads and was causing the test to get stuck because
it can't handle a timeout.
Sets the timeout in get_response_code to the test-defined timeout
Restores the original page and test files
Removes the select_option function
Implements @bobsilverberg's recommended changes
Adds select_option function for drop down select elements
Adds Get Mozilla Updates widget tests

Note that the `select_option` function is included in this because it's
used to select the country in the form.
Adds `get_response_code` back in because I accidentally removed it
Removes unused Timeout import
Fixes pep8 issue
Removes unecessary backslashes
Moves Selenium actions to page.py
Moves email form tests to about.py and other tweaks

* Changes the names of the locators and tests to be more consistent
with other email tests
* Adds a test to check if the form exists
* Adds a test to check if the form fields exist
