big refactoring #11 : replaced %lxOBJ by x%lx and removed nlet_tag from all iemgui, among other smaller changes

big refactoring #10 : simplifying the _draw_new, _draw_select, _new, _dialog methods, among other things

big refactoring #8 : fusion of [hsl] and [vsl] together, and fusion of [hradio] and [vradio] together

fix for commit d49dbfcc, which was missing the .h changes. Also removes some unused functions and moves [vu] stuff to g_vumeter.c

refactor : merge t_iem_fstyle_flags and t_iem_init_symargs into t_iemgui. remove type t_iemguidummy. remove fields x_rcv_able, x_snd_able and x_font. removed redundant arg "void *x" in 9 old g_all_guis.c functions. added dummy "send" method to [vu] for consistency.

*gop leaving stale vanila objects
*fixed bug where closing subpatcher of gop patch/abstraction redundantly opens gop patcher/abstraction
*fixed bug where reordering did not properly deselect previously arranged elements

first stab at porting core GUI to tkpath with SVG goodness. new scrollbars that will hopefully put an end to the old painful scrollbar nonsense. pdtk_tip clean-up and improvements. tons of other small bug fixes. a number of issues/wishlists still exist before the next big release:
*improve g_array lower/raise to use new functionality (BUG! doesn't match any items)
*scalar is drawn behind at first
*Scope~ window name "h16ffd10" already exists in parent (likely resize hook)
	*Change appearance of the resize hook
*better getrect for scalars inside plot?
*reenable bgerror and t_tkcmd catch
*Clean-up and merge cyclone documentation

all gop widgets (at least ones in vanilla release) have their nlets hidden when displayed inside GOP, as having them is entirely superfluous in that view

fixed gop getrect detection for objects that have been previously relocated to allow for consistent positioning

added ability for gop to intelligently detect when iemgui objects fit (or don't) inside gop window. the same also applies to dynamic changes to iemgui properties (size, font, label, delta, position, etc.)

fixed regression in the iemgui move handle for object labels where text would erroneously disappear as a result of a commit earlier today

fixed problem where using find/finderror would open the new window (where offending object is located) but would not properly select the said object

merged patches from https://sourceforge.net/tracker/?func=detail&atid=478072&aid=2947822&group_id=55736

fixed hacky offset in the original object that made it draw with a unique offset, rendering autopatching and tidy implementation cumbersome without ugly hacks. will break backwards appearance (it will appear with a few pixels offset)

Overhauled preset_node and preset_hub to support any kind of data, including symbols, floats, and lists. Removed unnecessary global class declarations and object filtering for node and hub.

Finished fixing inconsistency from the iemgui and non-gui fonts. This will break font appearance in older patches but looking forward will make things a lot more consistent. This is in part backported from the 0.43 branch.

fixed all iemgui objects to conform to the new model of gop selection (no highlighting of objects inside gop unless they are toplevel objects)

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).
