Add no_dot_prefix option

This utility can easily be used for synchronizing arbitrary
configuration folders with symlinks that may not necessarily be the home
directory.  I have encountered several use cases where the files that
I want to manage with 'dotfiles' should not/can not be prefixed with
a '.'.

Fixes #47
