Parts screen redesign

The Parts screen has an updated UI. It now uses more screen space with an updated layout to make use easier.

The distinction between adding parts to a document job group and adding / updating the local product database has been made clearer with separate sections. Additionally the part editing section (top) and search results (middle) have their own clear button.

Additionally there is a quick find filter on the supplier drop down and support for superseded parts has been added.
