Add IDL patches for CSS Typed OM and Payment Request (#213)

- CSS Typed OM: restore previous definition of CSSColor as new definition
references not yet defined CSSPercentishArray type
- Payment Request: restore PaymentAddress and AddressErrors interfaces, dropped
from the spec but still referenced by "Method Payment: Basic Card" and by the
Contacts API
