Death to Spork! Death! Death!
rails g scaffold notifications.
added cancan abilities for reading notifications
removed unwanted methods from controller
a bit of test cleanup
Removed "notification type" since WAGNI (yet)

We figured that doing without it was more like the simplest thing that
could possibly work.

Note that we edited the migration in place after rolling back.  This
would cause problems if anyone had downloaded the code from pozorvlak's
repo the other day and run it, but we're assuming they didn't (since
they wouldn't have got anything interesting out of it anyway.)
removing unwanted new/edit stuff for notifications
comments now generate notifications
changed to/from to recipient/sender
prettified notifications inbox etc
Show unread notifications as bold

The view here isn't as DRY as we'd like, but all the options were kind
of ugly, and this one was easiest.
added inbox link and count to nav
don't send notifications to yourself
Merge branch "notifications".
Prettifying the plantings page.

Added a couple of tiny methods on Crop, and delegated them across to
Planting, to easily display the default/first scientific name, and to
show the number of times a given crop's been planted.

Sadly, the tests randomly fail on my box saying "No route matches
{:controller=>"plantings", :action=>"show"}" which is just nonsense. I
have no idea why it's doing that, so I'm committing it anyway, in the
hopes that either someone can tell me what's up, or else it's just a
glitch on my dev box.
Minor tweaks to plantings page.

Tests still broken for me.  WTF is this even?
Merge branch 'dev' of https://github.com/Growstuff/growstuff into prettier-plantings
added 'where' to planting info (incl. location if known)
Fix one-argument calls to link_to.

Fixes broken tests.
Don't show () on plantings/show if no location given.

Can someone explain the semantics of nil and defined? to me?
