Including new svg sprites for ArchiMate

[jeanmarc]

I've discussed submitting svg versions of the ArchiMate sprites to PlantUML (see plantuml/plantuml#2310), and one step suggests to add these and an updated Archimate.puml to the plantuml/plantuml-stdlib repository.

The Archimate.puml is located in ./stdlib/archimate, but where should I store the ArchimateSprites.puml (containing the svg sprite definitions) so that it becomes available in a PlantUML build?

Alternatively, I could incorporate the sprite definitions in the Archimate.puml itself, which may simplify the inclusion of the svg sprites.

Happy to receive some feedback on how to proceed :)

Proposed #159

I'll close this discussion, as we've now incorporated the svg sprites in plantuml itself, and my latest PR (#161) should enable them for all archimate elements. The ArchimateSprites.puml is no longer needed and will be removed.
