Automatic generation of SKU identifiers for Isotope

This extension generates new SKU's for products you add to Isotope. It keeps a list of prefixes/suffixes and an auto increment value for that prefix.

After installation you can use the # character to generate an id at that spot inside the SKU.

For example, adding products in the order below with that value for the SKU generates an new SKU:

1. SKU: flowers# -> flowers1
2. SKU: flowers# -> flowers2
3. SKU: trees# -> trees1
4. SKU: tr#-int -> tr1-int
5. SKU: flowers# -> flowers3
6. SKU: tr#-int -> tr2-int
7. SKU: tr#int -> tr1int
8. and so on...

The numbers can be left padded with zero's, the padding setting is product type dependent and can be set at the product types. The next flowers# from previous example would become flowers004 if padding was set to 3.
