fixed color inconsistencies in gop and array objects when selecting/deselecting, introduced optimized redrawing of gop objects

fixed nlets not being properly selected after gop object has been redrawn, improved redrawing speed with gop objects

implemented universal catch{} for all commands sent from c to tcl to minimize (eradicate?) stderr output.

fixed regression where arrays did not get moved by tag, resulting in a much more inefficient displacement, fixed stray redrawing of nlets on multi-gop cut/paste_atmouse (workaround due to limitations of the networked model between the gui and the engine, fixed offset bug where object got displaced (as in duplicated) when undoing their deletion.

*fixed bug where objects were selected via a mouse click based on their left-to-right rather than top-to-bottom position
*fixed bug where undoing moving of a GOP object would incorrectly draw the object on top of other objects
*fixed bug where nlets would show on top of other objects when highlighted

fixed wrong color fill for selected gop object when opening gop-ed subpatch, incorrect selection of all scalars inside gop-ed patch when it is being edited as a toplevel window, and a bug where repeatedly opening already open gop-ed patch does not re-focus its toplevel window

Added undo font size, overhauled font resizing logic (x/y scaling is now bound to font resizing), added zoom option (ctrl+mousewheel), minor code clean-up, dynamic font resize improvements to the tooltip system and improved tooltip arrow appearance.

fixed automatic resizing of the gop when changing font sizes, complete overhaul of the tooltip engine. TODO: add proper nlet tags to iemgui objects...

by tag in which case gop will fall back to the old way of redrawing

altered behavior of gop objects so that internal elements are not visibly selected. Also reworked the way array and scalar selection is dealt with fixing segfault and making a more fool-proof way of selecting them.

improved logic for moving gop objects by checking if the gop has any legacy objects inside it that don't support displacefnwtag

fixed three regressions that crept in due to implementation of moving gop objects by tag. one of them manifested itself when an object was altered as gop and a sub-patch pops up asking to discard changes made to it. upon returning on the main window with the said gop, due to redraw objects were not reselected so dragging the object would not redraw properly even though it could be displaced, resulting in a seemingly stale gop object (in actuality it was simply displaced by being dragged while its visual content did not displace). Also, excessive stdout errors regarding redrawing gop resize handles and possible menu edit update has been dealt with.

Fixed segfault when creating undo for array apply (e.g. when changing array size). Also expanded moving by tag to arrays and scalars. Now, the entire array even with a ton of points is moving like knife through the butter :-)

Added support for moving GOP objects via tag and disabled showing of resize handles on iemgui objects when displayed inside a gop window (this became an issue due to new way of selecting gop objects which now also includes all objects inside it).

major overhaul of existing undo actions to conform to the infinite undo format, changed how undo create functions, started undo recreate, reformatted undo index, a number of minor bug fixes, implemented undo actions index 1,2,4,5, and 9 and started working on 10.

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.
