New XEP-0198 option: "max_resume_timeout"

Browse Source 
In the past, the "resume_timeout" option defined both the default resume
timeout and the maximum resume timeout clients are permitted to request.
Admins might want to allow clients to request a timeout value that's
larger than the default, though.  This can now be done by specifying the
"max_resume_timeout" option.
