Unicode libs x3

Complete re-write, and cleanup of all #ifdef statements, plus separated library calls away from GUI files so that they can be re-used in native scripting and python (this is not done but now available for anyone interested in writing such code).

namelist library code all funnels through the file "fontforge/unicodelibinfo.c" which contains three functions:
(1) inituninameannot() which existed in 20120731-b and likely called by programs that made use of the fontforge namelist library.
(2) unicode_name(codevalue)
(3) unicode_annot(codevalue)
