*fixed improper paste location for scalars due to incorrect casting of t_scalar to t_text to retrieve its x and y positions

*fixed incorrect getrect when selecting a plot with scalars at each point (see setsize-help.pd). This was a regression from an earlier "fix" (see https://github.com/pd-l2ork/pd/commit/f0916f85a11894a43067d5b07ae5f8eea2b2c1b9#diff-5ff2b78bd60b3b9c36db43b8d5f5c168). The latest code does not exhibit the said problem so this should be all ok.
*fixed embedded scalars at each plot point not being selected for displacement with tag due to clumsy way of labeling them. This is achieved by adding scalar arg to the parentvisfn which also alters g_canvas.h spec but also makes things more streamlined.

*Ported open_via_helppath from pd to fix inability to open help files when starting pd-l2ork from the doc/5.reference folder.

*forced array graphs to keep GOP/hidetext under all circumstances (later update properties window so that the GUI reflects this rather than printing info in the console)

*removed unnecessary logic for keeping carriage returns to avoid having an empty line at the top of the console after clearing console

*forced hidetext on all gop arrays to make its resizing sane. Later update properties to reflect lack of this option.

*fixed segfault when trying to create an object inside an array GOP due to incorrect check whether the object is an array in shouldvis function that is being called as part of gobj_vis to optimize (re)drawing

*made GOP aware of minimum size when having an array embedded inside it

added ability for comments to be navigated by rows (using up/down), as opposed to home/end which takes you to the beginning/end, or ctrl+left/right which takes you to the next space

backported comment resize marker, updated it to support pd-l2ork and selection colors, added fix to the resizable objects to support abstractions and subcanvases.

added forward mess patch by Jonathan Wilkes that enhances in-patch interaction (think: prancing ponies patch demo)

added updated help files for pdinfo, classinfo, and canvasinfo (by Jonathan Wilkes), merged patch by Jonathan Wilkes for the search-plugin.tcl with additional enhancements for tab/focus.

reapplied Albert Graef's patch due to wrong patch being applied for the delayed unbind. Still have to work on ensuring that there are no memory leaks in unique cases where an object unbinds a different bindlist when receiving a message to do so on another (faust being an example of this).

fixed cursor inconsistently failing to reflect topmost clickable object while ignoring non-clickable objects that are above topmost clickable object, both on main canvas and inside gop objects.

fixed long-standing bug where on GOP objects click registered on the first detected object, rather than the one that was visually topmost

added one more k12 object and updated pd.tk to reflect new items in the k12 menu (including new minimum size)
