*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

Merge branch 'master' of git://github.com/pd-l2ork/pd

Conflicts:
	pd/src/g_all_guis.c
	pd/src/g_vumeter.c

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)

give IEMGUI externals their own copy of the old functions so that the new impl of g_all_guis.c can evolve freely

suppress creation of drawcurve, drawnumber, drawsymbol and plot when the user tries to create them inside a group.  (Currently their click and motionfns don't take the parent transformation matrix into account)

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

fix bug about -d 4 not being applied on lines that follow a %s whose string ends in \n, such as all sys_gui
