Define command and bpatchers

I've been using the definesubstitution command extensively since I first discovered it, and I'm really happy to see the improved define command, which makes passing args/attributes to stereotyped objects way easier!

Although... is there a chance that we'll get a proper way to use this in combination with bpatchers in the future? At the moment, it's (afaik) only possible to pass arguments, not attributes, to a bpatcher upon creation due to how @args is parsed by the bpatcher. The only way to pass attributes to the contained object is by editing the @args attribute in the inspector.

At the moment, we can do something like

max define mybp bpatcher @name somebpatcherobject @args 123 456

but the only way for a user to override the default arguments (123 and 456) here is to override the @args attribute in its entirety (e.g. if you want to override the first argument:[mybp @args 999 456], instead of [mybp 999]), and there's no way to pass attributes to the contained abstraction ([somebpatcherobject]) at all.

It would be pretty nifty if we could use define to wrap an abstraction in a bpatcher so that others could use it in the same way as they would use any native/external GUI object.

Also, so happy to see that bpatcher windows now are initialized to the size of the content rather than a fixed 128x128 window!!
