Board sections moved to the sidebar

The menu became a sidebar block

Board sections used to hide in the "Board" dropdown above the columns. We moved them into the sidebar, into a "This board" block — it appears whenever a board is open, right above your profile at the bottom.

Now within reach, no extra clicks:

• Wiki — the board's pages and documentation;
• Discussions — every task comment thread;
• Analytics — completion charts, trends and leaderboards;
• Archive — done and dismissed cards;
• Settings — for those with the rights (not everyone sees it);
• Start sprint — appears when there's no active sprint.

Why

The area above the columns got roomier, and sections stopped hiding behind an extra click — moving between the wiki, analytics and the board is now as fast as moving between boards themselves. When the sidebar is collapsed, everything stays available as icons with tooltips.
