Fixed nasty bug where doubly-embedded pd canvases (not abstractions) did not redraw properly (affects all known versions of pd) plus additional clean-up and improvements on the gop redrawing/apply logic including ability to limit minimum size on gop-enabled objects without parents that also do not have hidetext enabled.

added gop move/resize via gui, improved logic on autoresizing objects to accomodate space for nlets (GOP-ed objects with hidden text can be of just abuot any size)

Cleaning up code plus attempts at improving script-based dynamic closing/opening of patches (as per Jonathan's request).

*fixed graph-on-parent enable/disable does not activate undo/redo on the parent window (or the gop-ed patch unless it is open)
*improved verifyquit mechanism to accomodate abstractions
*fixed bug where hide text value was not properly interpreted by the canvas apply redo/undo
*fixed stray stderr tcl/tk errors

Cleaned-up paste from external text into canvas feature, enabled the said paste action, and added ability to relocate and resize canvas as part of pasting into an empty canvas. If pasting into a canvas already populated with at least one object, the paste of the said information ignores canvas properties and pastes objects at mouse

Fixed segfault when trying to paste partially copied (and thus erroneous) patch from an external source (e.g. a text editor) where the copied contents contain only "connect" instructions.

Added universal copy and paste allowing importing of patches by copying and pasting the text directly into the patch. Still need to decide whether auto-resizing of the window is also desirable (there are both pros and cons).
