*added ability to have spaces in iemgui properties dialog

change type of scalehandle_new and h_master. Document some structs in g_all_guis.h and change some field sizes.

*cosmetic fixes to g_canvas.c

remove canvas/glist arg in a bunch of recently added iemgui functions, and introduce iemgui_draw_move & iemgui_draw_config

*improved g_all_guis.c and detection/drawing of handles

*fixed remaining g_number.c regressions. Now need to match this with the rest of the iemgui objects.

*fixed handle behavior on iemguis (current implementation is not equipped to deal with config kind of actions, and it does not have to)
*streamlined GOP handles since now draw_select deals with explicit delete before redraw

*fixed send and receive functions so that they properly update number2

*added selected tag to scalehandles since they should only appear when things are selected (or as is the case with GOP, when nothing else is selected)
*fixed regression in number2 where after dialog it requires complete redraw

Still need to fix the label reselection after it has been added/removed.
*fixed vu meter having bogus scale values when changing the label and some out-of-sync selection issues with the dialog. Needs to be vetted like number2.

*began working on clean-up of iemgui regressions and preexisting bugs (still need to figure out inconsistency with the hiding/showing of nlets, as well as inability to displace number2 after it has received a label message)

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

*cleaned up formatting to make source more legible

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

*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
