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.
