Introduce 'rate_limit' option of mod_avatar

Browse Source 
The option controls how many avatars a user can upload per minute.
The option takes positive integer values. The default is 10.
Note that the option only takes effect when an avatar is about
to convert to a different format, i.e. it implies that `convert`
option is configured.
