Respond differently to status code classes

from @maelle

Maybe we should respond differently to different HTTP status code classes.

Change default type of response:

• 1xx-3xx: message (only a message is given, so no stoppage of code execution by default)
• 4xx-5xx: stop (definitely an error, so we'll stop with error message) (use can also choose warning)

Muffling on a http() call (optionally don't respond at all):

• 1xx-3xx: if muffle=TRUE, return http response class invisibly
• 4xx-5xx: if muffle=TRUE, it's ignored since there was an error

that is, muffling only applies to 1xx-3xx statuses
