Translate docs with po4a (#2590)

* [i18n] Add docs po4a script

* Add proof of concept

* Add a few more translations

* Hush ShellCheck and shfmt

* Make that list po4a-friendly

* drat, this document could've probably been auto-generated

* Definitive proof that it's translated from French ;-)

* Add some brand spanking new French translation

* More translation

* Mostly finish that config page

* Fix up FAQ

* More contributing

* Dev first steps

* Let's ignore that admin stuff at the very least for now

* Translate release new version, make French the source first and copy all translations

Then replace French with English in the source.

Much quicker than any alternative route.

* And add the English translation

* Minor stylistic leftover from French

* Most of first steps

* Forgot the extensions

* Use po4a 0.56 to get rid of way too many newlines

* Fix up those newlines

* No point linking to Firefox integration anymore from the new user guide

* Start on main view

* A bunch of main view stuff

* More main view

* And some subscriptions before going to bed

* First steps for devs

* More dev first steps

* Incomplete French → English dev/GH translation

Because I need to ask about that mailing list thing

* Fix typo in docs/en/developers/02_Github.md

* Translate & complete devs/github to English

* Fix up most of extensions

* Is that supposed to be a non-breaking space? Let's see

* Match up some users/mobile access

* More users/mobile access

* Add fresh French translation to Fever API

* Fix typo

* Match frontend todo thingies

* Fix a typo

* Some extensions strings

* Remove Fx subscription service from the docs
