Subject: [PATCH] Refactor copies and composites (#2316)

* working toward phasing out copy
  - macros and copies behave the same way
  - combine plain macro and plain copy attributes into implicit prop attribute
  - if no prop, name applies to replacement (no assignNames)
  - if prop, still applies to copy, use assignNames for pieces
* the ability to copy componentIndex from non-standard composites
* updateValue, animateFromSequence handle target subnames and subnames component index
* Actions always await performUpdate and similar
* render composite replacements with commas
* assignNames, componentIndex skip only blank children
* correctly copy with no-link copies of a prop
* aslist attribute for additional composites
