Visual regressions in the lhnavigation widget:

- Even though I like the collapsed left hand menu, I'm not sure it's good enough from an accessibility point of view. Is there something collapsable that can be done instead (something along the rough lines of http://www.theblaze.com/wp-content/uploads/2011/10/Facebook-ipad-left-hand-nav.jpg)?
- We can probably give the lhnavigation a bit more width when it's shown in a small window
- The items are vertically a bit further apart than they used to be
