JSPROP definition does not allow patching arrays

[rsto]

There is an inconsistency between the JSPROP definition in the JSContact/vCard conversion document and the definition of the PatchObject in the JSContact spec. The JSPROP definition states:

The pointer MUST NOT reference into an array.

but the PatchObject allows patching existing array members. We had to allow patching array members to make localizing name and address components efficient, as well as better supporting phonetics in these properties.

We should consider removing this restriction from JSPROP in a future update of the spec.
