Summary: [initbang]/[closebang] for patch constructor/destuctor
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.

for reasoning why this is needed, see the pd-dev archives

the 2nd patch additionally implements a [closebang] object, which gets called just before a canvas is destroyed.
note that the patch (cloeinitbang.diff) holds both the closebang- and the initbang-changes; do not! apply both patches
