Sprite resource fiddling

* ROM sprite sets for Ursula and Morris4 brought in sync with Iyonix and Sovereign, including creating new sprites where missing
* Disc sprite sets created for Ursula, Morris4, and Sovereign. These may not be coherent yet, but are the superset
* Shelved the crusty 2D templates and tools
No code changes, nor resource changes to active ROM builds, retagged as Wimp-5_17.
