Various improvements to functions lib
- Set xtrace verbose mode (-x or +x) - Added systemd-nspawn alternate to chroot - Fix message display of multiple paramaters - templateDir was missing quotes around element which could end up splittng a directory that contained spaces - added functionality to find template flavors within $SCRIPTSDIR and not have to be located within a sub-directory - Added a few more comments
