Function _affiliates_set_default_capabilities
Determines the default capabilities for the administrator role. In lack of an administrator role, these capabilities are assigned to any role that can manage_options. This is also used to assure a minimum set of capabilities is assigned to an appropriate role, so that it's not possible to lock yourself out (although deactivating and then activating the plugin would have the same effect but with the danger of deleting all plugin data).
