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.

* update scalar's array elements when drawing instruction attributes or transform changes

*ported fixes for crasher when sending a "dsp" message to tilde objects.  Backported from Pd Vanilla commits [8019b5] and [5769c5]

*fixed bug where patches with relative paths and multiple patches did not open properly within the existing instance of pd-l2ork

*tested and fixed compliance with ports of sarcduino objects so that their channel numbers correspond with those on arduino uno board
