[PD] "get" method for Pd

[katja]

Say you'd have a [global] object, with a getter and / or setter for
things like dsp, samplerate, version etc. Obviously, some things are
gettable but not settable, like version or path/to/pd, and some things
are not even gettable in certain circumstances, like IOhannes pointed
out. The object would then give an error message which you can catch.
For local info you'd have another object, for example [this] for the
window, (like MaxMsp has [thispatcher]).
