Refactor PP5 comparison handling

Introduce PP5GalleryTransform, a transform that compares incoming templates
against a fixed gallery (thereby avoiding the cost of repeatedly setting up
pp5 galleries for the same templates).

Modify AlgorithmCore to support supplying Transforms to the right of the
algorithm string, in this case ! should be used instead of :.

Implement a method for setting properties after objects have been created

Surely this will save many bytes of source code.

This gives transforms a chance to update their state to reflect any
changes made.
