Ansible: Symlink dotfile tasks

Add a new tasks file for symlinking a directory. Doing it this way instead of
stat'ing the file and forking based on its type in symlink_dotfile.yml is more
efficient, I think?

Clean up file permissions: remove other permissions.

Add a variable to toggle skipping symlink errors.
