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).

*Base path (for open/save dialog) is now updated when opening file from the command line to the directory of the file being opened

*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

Removed show-stopping bug in addsemi that was added while debugging segfaults with canvas undo/redo.

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

and even more cleanup (make distclean before committing)... still trying to figure out this git thingy...

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.

further fine-tuned the external buffer copy/paste logic to avoid redundant reloading of the clipboard

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).
