Merchant and Admin: Allow 2nd level properties in products.

This feature is about the ability of the merchant/admin to create a basic product and within the product allow the creation of properties to it with configurable limitations to it. And also for the customer (Shop Mobile (Web) ) to allow to select the product and purchase selecting those properties.

An example of this would be to select pizza as the product and a 2nd menu opening enabling to select the taste, say pepperoni, Italian, 4 cheese, etc.

Another example to illustrate the need could be to select a "kebab" and within the product have... say 2 options that can be selected: (1) no onions, (2) no cheese, or maybe both.

Another example is if asked an ice cream as a dessert, selecting ice cream and then enabling to select 2 flavors at most within maybe 10 flavors.

2 hierarchy product creation can now be avoided by creating in the main menu all product combinations, which can be really a lot (between 40 and 100) in some cases so this possibility has reached a natural limitation.

I hope I have managed to illustrate the need without any screenshots.
