Backspace 1.1.0

Backspace 1.1.0

Backspace now speaks English, Russian and German.

Pick your language under Settings, Account. On first run the app follows
your browser's language and falls back to English; once you choose, the
choice is remembered on that device. Every part of the app is covered: chat,
direct messages, voice and screen sharing, spaces and their settings, friends,
the instance settings, the mobile layout, and the desktop app's tray, menus,
recovery page and instance picker.

Dates, times, numbers, percentages and file sizes follow the selected
language too, so a German user sees "5. Sept." and "1,5 MB" and a Russian
user sees the plural forms their language actually has.

Errors from the server arrive with a stable code and are shown in your
language. Older clients and federated instances that do not know a code
still get the English text, so nothing breaks across versions.

The Russian translation comes from st7105, who translated the whole app in
#45 and whose work carried over
into this release with credit on every commit. Thank you. German was written
and reviewed by the maintainers.

If a phrase reads wrong in your language, open an issue or edit the catalog
under packages/web/src/locales; the consistency check in the build tells you
when a key is missing or a plural form is off.

Also in this release: the Flatpak build can use the webcam and talk to the
system power service, so video calls work and the app can keep the system
awake during a call. Thanks to st7105 and gr1n-the-big-floppa for that fix
(#93).

Note for self-hosters: the container image for this version failed to
build, so there is no 1.1.0 image to pull. Use 1.1.1, which is this release
plus that fix: https://github.com/TheZwiss/backspace/releases/tag/v1.1.1
