[PD-dev] Prefixed target with [remote] (maxlib)

[Maurizio Umberto Puxeddu]

Hello.

The attached patch is meant to enable [remote] to automatically prepend
a string to all the incoming message targets.

[remote pippo]

will forward messages to "pippoA", "pippopluto" instead of "A" and
"pluto".

The typical use would be sending messages to local target. So

|A 10 20 30, B 100 200 300< -> [remote $0-]

would forward the message "10 20 30" to "%0-A" and "100 200 300" to
"$0-B".

Can this be included in the original version?
Should I make another class?
There was an easier way?

Thanks for everything.

Maurizio Umberto Puxeddu.
