Topics with long names cause some UI issues

[lukas-shawford]

If a topic's name is really long, it causes ugly wrapping in the sidebar:

It also causes the the Edit button to be displaced in the main content area:

Not sure yet what the best approach would be to deal with long topic names. Ideas:

• Truncate long topic names with ellipses in the sidebar, and don't allow wrapping.
• Make the sidebar resizable by dragging (would need to remember the user's preferred width)
• In the main content area, topic names should probably wrap to the next line. The edit button should stay in place regardless of how long the topic name is.
