An attempt to open a brand new Mastodon instance configured
as SINGLE_USER_MODE=true will cause an exception.

Enable temporary registration if we have no users in the database

Fixes #1817

* Correct site_contact_email typo

* Separate about more page into partials, add specs

Devise changed their approach -

This change silences a deprecation warning about `TestHelpers`

* Add eslint-plugin-jsx-a11y.

* Fix npm script.

* Adjust npm scripts so test also runs lint.

* Fix existing lint errors.

* Don't break on a11y issues.

* Add role and tabIndex.

* Add vim and Mac files to .gitignore and .dockerignore.

* Handle htmlFor (partially), a that's actually a button.

* Fix missing tabIndex.

* Add cursor:pointer to load-more

* Revert change to load_more.

* Fixes based on review.

* Update yarn.lock.

* Don't try to install fsevents on Linux (hides warning noise).

* Add recovery code support for two-factor auth

When users enable two-factor auth, the app now generates ten
single-use recovery codes. Users are encouraged to print the codes
and store them in a safe place.

The two-factor prompt during login now accepts both OTP codes and
recovery codes.

The two-factor settings UI allows users to regenerated lost
recovery codes. Users who have set up two-factor auth prior to
this feature being added can use it to generate recovery codes
for the first time.

Fixes #563 and fixes #987

* Set OTP_SECRET in test enviroment

* add missing .html to view file names

simple_form.es.yml

* Fix typo: Aute/ción. should be Autenticación

* Add getting_started.apps
* Add search_results.total
* Fix notifications.settings

* Coverage for account being provided

* Start to refactor account search service

* Isolate query username and domain methods

* Isolate exact_match method

* Extract methods for local and remote results

* Simplify local vs remote and account isoliation

* Extract methods for local and remote results

* Simplify de-dupe of exact match

* Simplify logic to check for non exact remotes

* Cache some methods

* Remove nil from exact_match from results array

* Return exact matches first

* Use find_remote even with no domain

Account.find_local is just an alias for Account.find_remote(user, nil) - so we
can not bother with the conditional here, and call find_remote directly.

* Refresh local info for remote accounts when webfinger returns new values

It only refreshes account info if one of the URLs or the public-key changes,
in which cases it refreshes the full info, re-downloading the feeds from that
user.

Some special handling should probably be done when the public key changes,
but I have been unable to find any use for it in Mastodon yet.

* Re-fetch remote users we aren't subscribed to.

This might induce performance issues, we might want to only do that for users
we explicitly attempted to subscribe but failed to.

* Refactor changes

* Do not refresh existing remote account details more than once a day

* Avoid re-fetching webfinger info in tests unless otherwise specified

- Add some spec coverage for both methods
- Add explicit constant call-outs for where the params are from

* jslint: remove trailing space

* jslint: fix no-nested-ternary issue

Follow the jslint [no-nested-ternary](http://eslint.org/docs/rules/no-nested-ternary)
rule. Rewritten ternary with if-then.

Very light grammar fix to improve gender-neutral
