Add Echo support, minor dropdown/search visual changes
- Add an "extra personal tools" area for Echo support. Note Echo's icons are dark by default, which clashed with the white text in the skin by default… this can be worked around using CSS though. (Perhaps in the future we should set them to white by default? Something to discuss. At the very least we should provide instructions on changing the colors in the documentation.)
- Give the dropdown triangle a high enough z-index that it doesn't appear within the shadow of the actual dropdown tray
- Widen search bar from 11em to 15em
