document a bug for unit-circle.pd in todo

changed the GUI message parser to try to deal with newlines and old style tcl messages at the same time

fixed strange regression with gop scalar (or garray) having a crazy bbox because of scaling in the parent.

finally have a successful workaround for allowing cut/copy/paste/selectall/undo/redo inside an object box. The workaround allows object box editing without sending any data to Pd.  Once the box gets instantiated, the full contents are converted to FUDI and forwarded to Pd.  Seems to work so far.
