Better page layout

[mariha]

There are number of issues with the current page layout:

• the left side bar - navigation does not scroll so it is cut on smaller screens and there is no place for more menu options
• Open Collective link overlaps with the navigation - Layout glitch under weekly meeting sidebar #37
• no place for docs or blog subsections - Add docs section #44
• no icons for social media
• no [edit] text or button to make it inviting to propose fixes

See also #12 and #14 for proposition of content changes. Should be improved separately.
