Document how proposals work

[tensojka]

Core proposal functionality should be documented from a usage/deployment perspective.

• various contract types
• adding custom proposals
• arbitrary proposals
• when do proposals pass, express proposal passing, the different quorums

Code documentation (to be generated in the future) is outside the scope of this task.
