Update git submodules
- Update Timeless from branch 'master' to ac378626462773628e8d33d60c74acf866725c9c
- Merge "Make personal menu header expand to show (more of) full usernames"
- Make personal menu header expand to show (more of) full usernames
- Lose the special casing replacement labels for long usernames and just truncate in CSS with '...' or whatever
- Fix weird padding on two-column mode
- Possibly cleaner Echo badge/whatever handling
- Alignment fixes in general
Note: Breaks two-column layout for IE9-. Probably easily fixed (don't apply that one line to it), but I don't know how, and don't care.
