Contractor Link Tweaks

I've tweaked a couple of features involved in linking Contractors back to permit records. When you choose "Contractor" as the Applicant Type, the Applicant Name field will now be filled in with the Contractor Company info if there is no person's name in the Contractor record. The second feature is a simple prompt to also fill in the Contractor field in the Zoning, Other Permit, or Extra Permit screens when you choose "Contractor" as the Applicant Type and link to a contractor in the Contractor database.
