Affiliates

I would like to propose the extension of the affiliate plugin.
It would be nice if you could create multiple levels, each with certain commission levels.
Example:
Level 1 - 10%
Level 2 - 10%
Level 3 - 5%
Level 4 - 3%
Level 5 - 2%

Payments or royalties should be monthly basis.

That would be cool :slight_smile:
