Summary: [initbang] for abstraction-constructor

Initial Comment:
attached is a patch that adds a new object [initbang]
to Pd.

This object is similar to [loadbang], however it gets
executed just after the rest of the abstraction is
built and _before_ the parent of the abstraction is
finished.

reasoning:
this object allows abstractions to have a runtime
constructor (similar to the <object>_new() constructor
of c-externals); the [initbang] is emitted before the
parent patch is finalized, thus allowing the
abstraction to add inlets/outlets depending on its
arguments).


caveats:
a similar method for the abstraction _destructor_ is
still missing.

i haven't implemented an "initbang" message to the
canvas to rerun the initialization again.
