Update all translation forms that use this "counter" element.

* Small localisation enhancement.

Be consistent regarding "e-mail" vs "courriel": I suggest
using "courriel" to refer to the electronic message and
"e-mail" when used in "adresse e-mail".  This reflects
the usage I generally observe, but I may be wrong.

* Localisation enhancements.

Omit some commas: "..., ..., ou ..." should be "..., ... ou ..."
since "ou" already articulates the sentence.

Also replace "demande" by "requête" when it makes sense.

* selectively Revert "Fix regressions from #2683 (#2970)"

This reverts commit 72698bc3b4.

* Revert "Handle hashtags in spoiler_texts (partial fix for #699) (#2683)"

This reverts commit e2491680e6.

Resolves #2515

for this file.

Got an error in asset precompile on Heroku:
Module build failed: Error: ENOENT: no such file or directory, scandir '/tmp/.../node_modules/node-sass/vendor'

* Framework for delivery worker spec

* Refactor of pubsub delivery worker

* Fix color contrast some more in privacy warning

Latest master appears to have changed the <strong> to this unreadable grey color. If you want that to be white then it should be pure white. If someone would rather revert this to that strong dark blue color it was before that would be good too.

* Make domain dark blue again

* add missing ;

woops

* Allow SCSS variables to be overridden with
  `app/javascript/pack/variables*.scss`

* Allow these SCSS variables to be overriden:
  * `$base-shadow-color`
  * `$base-overlay-background`
  * `$base-border-color`
  * `$simple-background-color`
  * `$primary-text-color`
  * `$valid-value-color
  * `$error-value-color`

* Add <ostatus:conversation /> tag to Atom input/output

Only uses ref attribute (not href) because href would be
the alternate link that's always included also.

Creates new conversation for every non-reply status. Carries
over conversation for every reply. Keeps remote URIs verbatim,
generates local URIs on the fly like the rest of them.

* Fix conversation migration

* More spec coverage for status before_create

* Prevent n+1 query when generating Atom with the new conversations

* Improve code style

* Remove redundant local variable

so that when a reblog parse fails on another instance, it doesn't
look like a misattributed/stolen text

The current text contrast on the privacy warning is a WCAG violation. I didn't notice this because my instance has a custom theme which is better. On default theme I am barely able to read the text with my impaired vision. This patch brings the contrast to Normal Text WCAG AA compliance, and Large Text WCAG AAA compliance.

Sidekiq doesn't need a port, however that env var is used for generating URLs
in development, so when foreman sets it wrong, you get bad URLs from the
streaming API during development

* Normalize locales

* Restore "mention" locale key

Use ES Class Fields & Static Properties (currently stage 2) for improve class outlook.

Added babel-plugin-transform-class-properties as a Babel plugin.

Remove unnecessary messages added in #1879.
It is duplicated with other keys, causing the correct message not to be displayed.

Use https://github.com/heroku/heroku-buildpack-apt to
install protobuf-compiler and libprotobuf-dev which are needed by cid3

* Add yarn-error.log to gitignore

* Add yarn-debug.log to gitignore

Updating some arabic translations.

* Update doorkeeper.ar.yml

- Remodelling doorkeeper.ar.yml and adding missing strings from english version to arabic version.
- Translating max strings
- Reviewing some translations
- Other strings to be translated later (complicated somehow)

* Update doorkeeper.ar.yml

Updating translations from lines : 88 to 91

There are some dependencies that are no longer needed anymore.
As a result, it took more time to install the package than necessary.

I want to delete them and shorten the installation time.

Fix #2221 - Catch OpenSSL exceptions when loading remote avatars/headers/attachments
Don't strip "rel" attribute from <a> tags when sanitizing (microformats)

* Fix test

Receiving instances will then use their own missing image

Also, add <content /> to deleted statuses, since there was a reported
problem with the deletes and GNU social
