[PD-dev] change in how declares are interpreted from within abstractions

[Miller Puckette]

To Pd dev:

I just pushed a change that I believe to be a bug fix - now, [declare -path foo]
inside an abstraction looks for a subdirectory "foo" relative to the directory
that the abstraction was found in, not the calling patch.  I think this doesn't
break anything but since search paths are so confusing I thought it a good idea
to mention the change here in case anyone sees something wrong with it.

cheers
