Clothing and pronoun fields (#2689)

* Clothing & Gender fields: Add to database [MODIFIED TO NOT DEPEND ON SAPHIRE-DB-REFACTOR]

Sorry about this, Saphire.

* Clothing & Gender fields: Add UI [FALLBACK II]

* Clothing & Gender fields: Actually apply gender

* Clothing & Gender fields: Import innerclothingskirt field from my previous attempt

Couldn't import actual prototypes because of a change to IDs

* Clothing & Gender fields: Add innerclothingskirt field to everything

* Clothing & Gender fields: Jumpskirts now work

* Clothing & Gender fields: Gender field will follow sex field if it's not different (UX improvement) [FALLBACK II]

* Clothing & Gender fields: Gender -> Pronouns to reduce confusion. Also, fix profile summary. Properly. [FALLBACK II]

* Clothing & Pronoun fields: Refactor so that profile equipment adjustments are performed in StartingGearPrototype.
