Limit category selection in vendorprofile

It would be best to show only categories in which there are products of the vendor to avoid blank output after filter apply.

There is an option for this in VMV settings (vendor profile tab -> Show Products category filter ->Yes, current vendor's only categories )
, but this is very ressource consuming and might crash the server if Vendor has hundreds of items.
This why there also is a product counts treshold setting (following field), if you set this option on, to make sure it won't be applyed to vendors with more than x products.

Hope it makes sense.

Oops, sorry for inattention.
I'll check the code, may be it possible to reduce consumption right for me - you know, if you know what you want you can reduce the conditions. Thank you for hint.
