New Feature - create a product with variants from a hash of option types & values

[citrus]

This pull request adds the ability to create variants for products from a hash of option_types and option_values. Basically you can do something like this:

rails console

size = Spree::OptionType.create(:name => "size", :presentation => "Size")
%w(Small Medium Large).each do |name|
  size.option_values.create(:name => name.downcase, :presentation => name)
end

color = Spree::OptionType.create(:name => "color", :presentation => "Color")
%w(Red White).each do |name|
  color.option_values.create(:name => name.downcase, :presentation => name)
end

options = {}
Spree::OptionType.all.each do |ot|
  options[ot.id.to_s] = ot.option_value_ids
end

puts options
#=> {"1"=>[1, 2, 3], "2"=>[4, 5]}

product = Spree::Product.create(:name => "Zomg!", :price => 5, :option_values_hash => options)

puts product.variants.count
#=> 6

Why?!

...so we can create new products & variants from prototypes! Once you select a prototype from the new product page you'll get a group of checkboxes for each option type and it's option values. Select whichever type/value combo you'd like then click create. Now visit the product variants page and see your newly created variants.

If you'd like to see it in action, just check out the video:

Specs are included and all are passing 🍺 🍺

This will save lots of time during multiple product creation! Instead of having to manually create the variants over and over. You basically create it once in prototypes and boom! Nice work!
