* View voter list as it is in voter file upload

* Display the login type again.

* Returning to the source fixed-size fonts

* Add a proper label you can easily make selections.

* Make cast vote email a template

* Catch non json results when verifying election

If you try to verify a election and you aren't allowed, you get the following
error. This is because it is expected a JSON result and you get, for instance,
a html page to login.

VM65:1 Uncaught SyntaxError: Unexpected token < in JSON at position 0

* Alter request.REQUEST to request.GET

Step toward future django version upgrade
Currently, the following warning is received:
RemovedInDjango19Warning: `request.REQUEST` is deprecated, use `request.GET` or `request.POST` instead.

* Fix to consider request.POST or request.GET

* upgrade gunicorn

* upgrade python

* upgrading to heroku-16

* Remove spurious comment

* correct # of votes

* Tweak style for textarea size

* Show trustee key in a textarea instead of open tab

Google Chrome raises the following error when trying to show
trustee key content as top frame data URL:
"Not allowed to navigate top frame to data URL"
See:
https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/GbVcuwg_QjM%5B1-25%5D
Tested in Firerox 64.0.2, Chrome Version 71.0.3578.98 and Safari Version 12.0.3

* updated software versions

* added workaround for gce for travis as per https://github.com/travis-ci/travis-ci/issues/7940

* Remove unused import causing deprecation warning

Warning in the form:
RemovedInDjango19Warning: "ModelXYZ" doesn't declare an explicit app_label
Apparently this happens because it tries to import models before app
configuration runs

* upgrade google APIs

* Ignore .idea folder

* Do not try to run more commands if any fails

* import and serve only enabled auth systems urls

* Prevent trustee enumeration by returning the same 404 error both if trustee is not found or secret does not match

Also, return a different 404 if election isn't found (instead of redirecting to home)

* Add missing import

* Dispatch worker method explicitly

* Reduce cluttering and overlapping on imports

* Order loaded voter files by date

* Update random.js

Setting randomWords paranoia level to 6, which is the default level suggested on https://github.com/bitwiseshiftleft/sjcl/wiki/Symmetric-Crypto#generating-random-bytes
Also removing unreachable line at end of function.
