Styled search results page

A bit of preliminary style for the search results page to match the Generic Search Result mock-up :)

* Search has been tweaked to search for crops and then any guides associated with those crops. It would be great to eventually be searching guides as well as crops.
* Crop images are placeholders
* Ratings are placeholders

More to come! Thanks for the help @rickcarlino and @roryaronson. @simonv3 mind checking that I'm following style here? I know some of this could be cleaned up with some mixins and different selector strategies >_<
Yes, totally agree. Keep forgetting about that actual traffic. I'll get a placeholder in until we get images in for crops.
