*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
*committed http://sourceforge.net/p/pure-data/pure-data/ci/97851b3c44b2b3839069928d90ca6185de4455c5/

fixed regression where iemgui widgets within GOP sometimes got redrawn even though that was completely unnecessary

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.)

improved/sped-up gop redrawing when using non-accelerated objects, fixed glitching when the two are mixed, improved zoom feature when using embedded patchers (since they share the same font size)

*creating abstractions from menu does not dirty the canvas
*add minimum and currentvalue in addition to maximum of the signal magicglass
*first tests in improving consistency of fonts between vanilla and iemgui objects (in progress)
