Unicode support for strings

Add suport for using unicode strings in .scad files. Support iterating
across them/accessing them via [] and searching.
--------
Add GLIB (to build for test and normal build -- both with installed and
built locally development files).
Add support for unicode chars to length and search builtin functions and
[] for strings.
Added unicode testing functions.
Ad GLIB to library info page.
