#235 custom converter for collection elements

[Tom Van Rossom]

Dozer supports "custom converters" for mapping fields from 1 type to another type.
Dozer supports mapping elements from a collection to another collection

But dozer does not support the combination of these two.

I would like to map the elements within a collection with a custom converter. If I specify the custom-convert on field level, it uses this to convert the whole collection, not the elements within this collection.
