Cleanup followup

This pull request does a few small things:

- Tighter copy on node list for  to decrease the chance of an ugly line break ( need better fix here so the line break is smoother). Just changed `also part of way %{related_ways}` to `part of way %{related_ways}`. This needs a better fix to make line breaks indent properly, but this should at least help a little. (issue #185)
- Properly positioned 'nearby users' block on user page to be in the left column (issue #184)
- Removed `deemphasized` class from search results (issue #181)
- lighter highlight yellow  on changesets page
