Some pages should only be shown to users who have permission to send or
approve broadcasts. This commit adds a test to ensure that this is true,
and that we don’t accidentally regress the checks for this permission.
At the moment viewing a broadcast is limited to those users who have
the `send_messages` permission.
This doesn’t match how we describe the permissions on the team members
page
This commit makes it so that any team member can see a broadcast that’s
in any state other than `draft`.
Password managers will try to guess what they should save as a username
by looking at the fields on the page where you set up your password.
When registering from an invite the email address (what we use as a
username) is predefined, and only shown on the page as text, not an
input.
This commit also adds a hidden input field for password managers to pick
up.

This commit adds a new model class which can be used by any app to
interact with a broadcast area. A broadcast area is one or more polygons
representing geographical areas.
It also adds some models that make browsing collections of these areas
more straightforward. So the hierarchy looks like:
> **BroadcastAreaLibraries*
> Contains multiple libraries of broadcast area
> > **BroadcastAreaLibrary**
> > A collection of geographic areas, all of the same type, for example
> > counties or electoral wards
> > **BroadcastArea**
> > Contains one or more shapes that make up an area, for example
> > England
> > > **BroadcastArea.polygons[n]**
> > > A single shape, for example the Isle of Wight or Lindisfarne
> > > > **BroadcastArea.polygons[n][o]**
> > > > A single coordinate along a polygons
The classes support iteration, so all the areas in a library can be
looped over, for example if `countries` is an instance of
`BroadcastAreaLibrary` you can do:
```python
for country in countries:
print(country.name)
```
The `BroadcastAreaLibraries` class also provides some useful methods for
quickly getting the polygons for an area or areas, for example to
render them on a map. So if `libraries` is an instance of
`BroadcastAreaLibraries` you can do:
```python
libraries.get_polygons_for_areas_long_lat('england', 'wales')
```
This will give polygons for the Welsh mainland, the Isle of Wight,
Anglesey, etc.
The models load data from GeoJSON files, which is an open standard for
serialising geographic data. I’ve added a few example files taken from
http://geoportal.statistics.gov.uk to show how it works.
At the moment they will get a ‘technical difficulties’ error if they
try.
We probably want to do something around letting people self-approve
broadcasts in trial mode, but for now just telling them they can’t is a
better experience than ‘technical difficulties’ (and will probably be
close to what they should see on a live service as well).
