this fixes #43277457 - reversion of crop and garden
added test for remembering the right crop/garden
sorting gardens alphabetically, so behaviour is clearer
Merge pull request #97 from Skud/planting-defaults

Planting defaults
added .DS_Store to gitignore
Fixed the homepage so it doesn't look messy on phones.

Basically the "hero unit" was rendering horribly on very small screens
(eg. phones).  I've made it so that the hero unit is only shown on
"desktop" and "tablet" devices, not "phone".

I also moved the actual content of the hero-unit out into a partial to
avoid repeating myself.
made login page look like the signup page
Added recent_plantings variable

Wrote tests for recent_plantings, recent_posts, new_crops
Specify recent version of rspec-rails
Add RSS feed for plantings
