----------
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.
Update comments/messages for CGAL source of bad boost libraries

Add comments and change to a status instead of a warning (as we recover
nicely and it is a known issue in CGAL @
https://bugs.launchpad.net/ubuntu/+source/cgal/+bug/1242111)
Add in missed glib build dependencies for OS X and unix
Add specific tests for unicode len()
