Add "Get Directions" button to requests and quotes

Add the same "Get Directions" button that jobs have to requests and quotes, so it opens driving directions straight to the customer's address. When a new request comes in, an assessment visit at the customer's property is often needed before it can be turned into a quote, and currently the address has to be copied into a maps app or another CRM opened just to navigate there. Having the button on requests and quotes would also show the drive time before scheduling the visit.
