Pagination and rate limits

Lists take page and limit (max 100) and return meta.total and meta.next_page (0 = last page). Each key may make 60 requests per minute by default; every answer carries X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset. Hammering far past the limit locks the key temporarily. Heavy server actions are also limited per server per day.
