changed use of objects as payload input for json_encode, to associative arrays for consistency
added functions/methods for firewall groups: list_firewallgroups(), create_firewallgroup(), edit_firewallgroup(), delete_firewallgroup()
added checks for required boolean parameters
for setting the information, although the site configuration is returned whole as one object.
I also added a provisioning example that I use with our internal ERP that automatically creates, updates and deletes sites according to internal ERP
site information. I added a settings template that has a couple of the most useful defaults, like auto upgrade, country and locale.
