Added to server class the property functions_parameters_type, that allows the server to register plain php functions as xmlrpc methods (i.e. functions that do not take an xmlrpcmsg object as unique param)

let server and client objects serialize calls using a specified character set encoding for the produced xml instead of US-ASCII (ISO-8859-1 and UTF-8 supported)

let php_xmlrpc_decode accept xmlrpcmsg objects as valid input

'class::method' syntax is now accepted in the server dispatch map

xmlrpc_clent::SetDebug() accepts integer values instead of a boolean value, with debugging level 2 adding to the information printed to screen the complete client request
