Added selection on basis of product description (iProduct)

I have multiple devices identifying with the standard FTDI pid and vid, since 
our organisation does not have an own vendor id.

The devices (different versions of a PCB) identify themselves with different 
product descriptions, carrying a board revision. Therefore, selectively opening 
a device on the basis of the board version was needed, since serial numbers are 
unique per board version only.

See the attached .diff files for the modification. NOTE that the modification 
breaks the API.
