GitLab

The structure of the roadmap isn't meant to support more than 6 tabs, so some changes are necessary to show
the roadmap correctly.

- Grouped the first 2 years 2014-215 on a single tab.
- Added headers for each card
- The last tab is now "Future", and doesn't refer to a specific year, but it's meant to show updates that will be
implemented in the future
- Changed default card from 2019 to 2020

This commits removes the page 'Technical specs' and adds some technical info to the 'About' page.
The 'technical specs' folder and page were removed from the repo, from the navigation menu and
the footer (for all languages)

zh-tw, zh-cn, tr, nl and ar are untranslated

The Urgent tag is meant to show prioritary communications that the community should be aware of as soon as possible
'Community' will show all non-urgent communications and general blog posts

- NOWPayments
- Rexi
- Minko
- SideShift
- Bidali
- Edited InstaEx

The list of languages doesn't need to be translated, so there is no reason to keep it in the language files. Moved to its own
file (/_data/languages.yml). Now the language dropdown parses the languages from there.
This change is also needed for the migration to Weblate (which would ask translators to translate the language names).
