+added new activity: add property
+added button to property listing (no real function yet)
     - shows message when you click add at end of input
+added menu in property details (no real function yet)
     - was wondering about menu, since all tabs will be viewable in each property, why not condense all 5 options to 1 menu instead of 3: 2 options for property, 2 for tenants, and 1 for report
+updated icon
+added hints to add property
