Inputting an address should be easier when creating a new business contact

When creating a new business contact and adding an address it would be useful if there was text in each of the address line fields to indicate what should go into the address line i.e. Address line 1, Address line 2, Address line 3 (Suburb), Address Line 4 (City), Address Line 5 (State), Postcode.

This information is useful to allow users to know what goes into each field and ensures that the data is entered consistently. At the moment users will enter the address into as few lines as possible. Australia has strict formatting for addresses and so this causes issues.
