Limit the daily number of posts from a user

[featheredtoast (Jeff Wong)]

There is a post about user state descriptions that has been updated here. Specifically:

@sam

New user

Special restricted account for first day of usage or new accounts. new_users have special rate limits defined in site settings

• Trust Level 1 account created in the last 24 hours, or Trust Level 0
• Non staff account

Limits:

• Can only create a topic once every 2 minutes (rate_limit_new_user_create_topic)
• Can only create a post once every 30 seconds (rate_limit_new_user_create_post)

The blog should probably be updated as well.
