[IMP] Chapter 9: Ready for Some Action

Added Sold and Cancel buttons:
When a property is sold it cannot be canceled
When a property is canceled it cannot be sold

Added offer accept and rejected icon button:
When an offer is accepted:
 1. The selling price is automatically updated by button actions
 2. Status changes to 'Offer Accepted'
 3. Rejects all other offers

 Added  an onchange, which updates the status to 'Offer Received' when there is an offer.
