Add forward compat parsing of PackedVector4Array

Browse Source 
This new Variant type is being added in 4.3, and breaks compatibility with
earlier releases. By adding minimal parsing support (converting to plain Array)
we can at least open the scenes, and minimize the data loss when going back and
forth between minor versions.
