Merge branch 'addSkelCopy' into 'master'

copy skel files into user home

new functions were tested independently, but the entire j2 script is untested
if skelroot is given, it looks for skelroot/common/skel and copies all within to $home
otherwise, it looks for $home/../common/skel and copies that to $home

See merge request !73
