Params: Add parameter types for IP addresses in various forms.
New parameter forms are: IP address in the format "a.b.c.d" where a-d are from decimal 0 to 255. IP address with netmask which is an IP followed by "/n" where n is a netmask length in bits from decimal 0 to 32 or by "/e.f.g.h" where e-h are from decimal 0 to 255 and which is all 1 bits followed by all 0 bits when represented in binary. These can also be specified as an integral IP and netmask passed in separately. IP address with port which is an IP followed by ":p" where p is a port index from decimal 0 to 65535. These can also be specified as an integral IP and port value passed in separately.
