[FEATURE] Adjust Star Prism combo

[kaedys]

• Updated Starry Muse + Star Prism combo to no longer assume the Starry Muse + Motif combo is also taken.
  • If the Muse + Prism combo is enabled and the Muse + Motif combo is not, then Prism will replace Scenic/Starry Muse, but not Landscape/Starry Sky Motif.
  • If both are enabled, Prism will act as it currently does, replacing both the Muse and the Motif when available.
• Prioritized Prism over Starry Muse. I don't THINK it's possible to have both available at once, but just in case.
• Renamed a number of the PCT globals to match their English client names, and sectioned the PCT action IDs by category/association.
• Updated the icon pattern and combo name for the Landscape Muse/Motif and Muse/Prism combos.

Fixes #461

"Extra" is how they name the AoE spells in French yeah, sorry LMAO When DT released I didn't pay attention to the english names because I was learning the new spells in french first

Ya, I fully expected that the names the vars took on were effectively direct translations from the French client names =P
