[bug 1097168] AAQ - Use about:support API when available.

To test this, you need to:

* peep install the new requirements/dev.txt
* Add sslserver to the INSTALLED_APPS in your settings_local.py: `INSTALLED_APPS = list(INSTALLED_APPS) + ['sslserver']`
* ./manage.py runsslserver
* Open the Browser Console and run `Services.perms.add(Services.io.newURI("https://localhost:8000",
null, null), "remote-troubleshooting", Services.perms.ALLOW_ACTION);`
* Go through the AAQ flow for firefox: https://localhost:8000/en-US/questions/new/desktop. The green button should do magic without the addon now.

I think that covers it.
