Avoid some uses of html_safe

We can use `html_safe` on non-interpolated strings, since that's trusted content.

Ensure that test utility methods are marked as private

This allows us to enable the check for test method names.

Refactor test to use general basic_authorization_header method

There's no need for this test to have its own version of the method.

Use flexbox to position the close icon on the sidebars

This ensures that the text and the close icon don't overlap, regardless
of the length of the title. The title div grows to use all available
space, while ensuring the text breaks if necessary to prevent it from

Avoid various uses of html_safe

We can avoid using `html_safe` in various circumstances, through alternative approaches like i18n keys ending in `_html` or using `safe_join` to avoid converting via unsafe string types.

The `_html` keys approach only work for ActionView helper version of `t`, not the base `I18n.t` method.

Rename Notifier to UserMailer

It's a convention in rails to name your mailers with a Mailer suffix, and is also common to name the class after the recipient (e.g. User, Admin). So UserMailer seems a reasonable choice.

Use the db:seed task to load languages

This is seed data that should reasonably be loaded into every database,
even those that are otherwise empty (e.g. no geo data). Using the seeds
process means that it will usually be loaded by default, and is easier
to find for existing rails developers.

Invalidate existing sessions when changing email or password

As we don't have any way to actually find the active sessions for
an account we instead store a fingerprint in the session, and refuse
to use any session with a different fingerprint.

Delete any outstanding tokens when a user changes their email

This ensures that any tokens previously sent to the old email address
can no longer be used if somebody were able to access that address.
