Add clipart support to the asset set wizard

This changeset adds clipart support to the asset set wizard. There is
only one placeholder clipart image now but the code reads the
available images from the jar dynamically.

This changeset also adds "file exists - replace yes, no, always,
never" handling for the generated icons.
