Summary: fix crash on sending empty "obj" mesage to closed canvas

Initial Comment:
as described in bug #1525832, pd crashes when you send
a "msg" or "obj" message (without coordinates and
arguments) to a canvas that is not visible (e.g. closed).

this is due to the fact, that inthis case, pd
automatically goes into edit mode, so you can type in
the content of the object/message (it's like creating
an empty object-box with Ctrl-1).
this is a not so clever thing, when the canvas is closed.

attached is a patch that fixes this, by checking
whether the canvas is visible and refusing to continue
otherwise
