Implement an initial "character" creation page

[slifty]

Unclear if this will actually result in character creation vs group / household creation... but still!

This should be very much rooted in placeholders and should not make assumptions about the shape of various relevant assets until #2 is completed.

Here's what the creation process will involve from our initial brainstorming:

1. Character (group?) Creation
   - We should allow the player to bring their own identity into the game
     - Profession?
     - Identity (gender, sexuality, race, age)
   - Additional members of the group
2. Purchasing supplies
3. Pick your goals (win conditions)!

- Buy a house?
- Get a job?
- Education?
