Sigil: City of Doors

This one is mostly bugfixes and tweaks to existing systems, including the custom UIs for both clothing appearance changer (Clangeddin) and Change Self/Alternate Appearance (Leoric). We also have some area updates from Neerepha, tweaks to summons from Alersia, "Invisible helms" in the appearance changer from Leoric, a fix (finally) to white dragon tails and an improved crystal golem from Xndar, and thanks to Alersia the new golems should all be properly craftable now, and the new animal companions should be properly selectable. Also some NPCs for an upcoming Scintilla event.

Hotfix applied:

• Hairstylist area in OOC room no longer has destroyable placeables
• UI for clothing appearance changer now can color armor parts
• UI for doppelgangers no longer copies clothing, while appearance copying only works on NPCs.
