Title: First pass at image upload

Greetings,

Took a stab at #8.

For this PR I:
* Created a new model (Image) belonging to Crop
* Added a has_many to Crop
* Added a new nested POST route under crop for images for form submit
* Added a new controller Images to handle this POST
* Added an 'Add Image' link to the bottom of the crop table (I18n fo en included)
* Created a modal to display a file_upload field
* Display images in a slick carousel - Foundation states theirs is deprecated

Looking forward to your feedback!
