Copying protocol

• By default up.util.copy() can copy array-like values, plain objects and Date instances.
• Array-like objects are copied into new arrays.
• Unsupported types of values are returned unchanged.
• To make the copying protocol work with user-defined class, see up.util.copy.key.
• Immutable objects, like strings or numbers, do not need to be copied.
