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

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

*fixed drawsymbol scalars' double names
*improved build process for tkpath
*improved to-front/back logic

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

*fixed cord redrawing when objects got resized due to cut/paste of object's text
*ctrlleft,ctrlright, and shift variants all now properly navigate messages during editing, including single character atoms
*fixed regression where clicking on iemgui labels of gop-embedded iemgui objects also counts as a click on the object itself (e.g. toggle being toggled on/off)
*fixed regression when dynamically changing iemgui properties within gop as to when to hide and when to show it
*proper redrawing and reordering logic for arrange and dynamic changes to iemgui objects inside gop
*committed http://sourceforge.net/p/pure-data/pure-data/ci/97851b3c44b2b3839069928d90ca6185de4455c5/

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

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

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)
