	@description:
		This function allows performing simple D-Bus calls without executing
		an external process. This feature is available ONLY under unix:
		this means that this function is absolutely
		non portable (don't use it in scripts that you're going to distribute).
		<application> is the name of the application being called, <objectid> is the
		identifier of the object called, <function> is the function to be executed
		on the remote object and <parameter1>,<parameter2>,... is the list of
		parameters to be passed. The <function> name must contain the
		trailing parenthesis and parameter specification (see examples).
		The <bus_type> specifies the bus to connect, use "system" for systemBus or
		"session" for sessionBus. If it's leaved blank, it will use sessionBus.
		The parameters MUST be in the form "type=value"
		where "type" is the C++ type of the parameter and value
		is the string representation of the parameter data. Currently
		KVIrc supports only QString,QByteArray,bool,int and uint data types.[br]
		The returned value is the string representation of the returned
		data if the return type is known, otherwise it is the name of the data type returned.
		[br]
		If the service name is prefixed with "?" then the call is performed in "remote test"
		mode: no "remote" errors are printed and the function returns 1 if the call executed
		successfully and 0 if the call failed. This can be used with the very first
		call to programmaticaly test if the remote application is running.

		Convert an integer from host to network byte order.
	@syntax:
		<integer> $system.htoni(<value:integer>)
		<integer> $system.htoni(<value:integer>,<bytecount:integer>)
	@description:
		Converts the integer value in host byte order
		to it's network byte order counterpart.
		Since the conversion is carried at binary representation
		level you must specify the number of bytes you want
		the binary representation to have. Valid values are
		1 (no conversion), 2 (short), 4 (32 bit int) and 8 (64 bit int).
		If omitted, bytecount is assumed to be 4.
