Version 1.1

Made usability improvements as follows:
- New contractors are now automatically saved to the database when
hitting "submit." The "save changes" button is no longer necessary for
adding contractors.
- The Add Contractor form will no longer automatically reset when the
user submits a duplicate entry.
- A button has been added to the Add Contractor page to allow the user
to clear the form.
- Auto-clean has been adjusted to automatically scan for outdated
contractors when visiting the home page. The "Auto Clean" button has
been removed accordingly, though the old AutoClean page can still be
accessed via direct link.
