Update report generate to use the correct tag
add support for site save

update request function to support passing arbitrary xml string data
which is appended to the root element, since it's useful with site save
just to modify the results of a site config request
by default don't print the query being executed
support setting api version for adhoc reporting requests, as some newer
functionality isn't available using the older api version
