Affiliate plugin 1.2

Hi
I've just updated the Affiliate plugin to version 1.2.

There aren't many changes you will see in this version, but the backend of the plugin is moving towards a a more common affiliate framework for use in single and multi-site systems.

The main reason for releasing this update at this point is for the addition of a column in the multi-site systems super admin -> sites page.

This will highlight those blogs created from a referral and those that where then upgraded and is to make it easy to track down any issues that appear such as in this thread:

The column will look like the image below.

The update is available now from the usual place.

Thanks
Barry
