Preliminary support for supplying additional arguments to algorithms

This saves upwards of 3 lines of code!

Sadly, using setPropertyRecursive to set things interacts poorly with
ProcessWrapper (because child processes are constructed as needed, using
a string to build their algorithms) so drop that for now.

Allow users to supply additional arguments to abbreviations or pre-trained
algorithms (e.g. FaceRecogntion(a=b) is now possible).
Arguments supplied must be key/value pairs, not positional. Any listed
additional properties will be assigned to the first matching transform
using a pre-order traversal of the algorithm tree.

This avoids the need for the arguments of GalleryCompare and other
gallery comparison style transforms to be precisely aligned.

Update some brace placements.

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.
