Improved layout of member profile page

In doing this, I added some content areas for all pages on the site:

1) subtitle
2) buttonbar

These are intended to help standardise the layout of all pages.  On the
member page, the subtitle is the location, and the buttonbar has links
like "edit profile", "upgrade account", etc (or if looking at someone
else's page, then "send message" etc).

I also implemented subtitle/buttonbar on the crop detail page (the
subtitle is the default scientific name).

The rest is just refactoring and tests.  I've removed some view tests
and put them in feature tests instead.
Added map to member profile page
Removed underline on header area
Changed all h1 to content_for :title
Tweaked layout of crop page sidebar
Added seeds_by_crop_path routes and stuff
removed spurious console.log calls
Deleted old view tests for crops
