change to product names in bugzilla

[C. Boemann]

Hi

I've changed all those calligra-product to calligraproduct in bugzilla so they
match our application names. And calligra-karbon product is now just karbon

This was needed as dr.konqi uses the application name to find the product

This however means that you need to update any saved bugzilla queries you have 
to reflect the new product names

sorry for the inconvenience
