Added Report Logos to Assisted Setup

If the user chooses this option, additonal fields will appear which allow uploading pictures for the header and footer, as well as options to set the alignment:

This allows for customers, who have their logos already when setting up a new company, to set this up in the initial setup instead of having to do it separately at a later time.
