Osc remote options

[catfact]

add option for the single-argument OSC patterns /remote/[enc|key]/n d in addition to the 2-argument patterns /remote/[enc|key] n d.

this allows the remote function to be used with limited/inflexible clients like TouchOSC.

supercollider client code looks like this:

~norns_addr = NetAddr("norns.local", 10111);

~enc = { arg n, d;
	~norns_addr.sendMsg('/remote/enc', n, d);
};

// other option:
~enc = { arg n, d;
	~norns_addr.sendMsg(("/remote/enc/"++n).asSymbol, d);
};

~enc.value(1, 8);
~enc.value(1, -8);
