mod_muc_markers: Add option for @id rewriting, default off (may break some clients)
XEP-0333 was updated to clarify that stanza-id should be used
instead of the 'id' attribute when in a MUC. Some clients still
use the id attribute, which is why we were rewriting it.
Rewriting is bad because mod_muc advertises stable_id, indicating
that Prosody does *not* rewrite ids. Recent versions of Conversations
actually depend on this being true.
All clients should migrate to using stanza-id for markers. See XEP-0333.
