Personal syncing of dotfiles #5

Allow for automatic dotfile syncing upon any updates to a repository with FDFd?? (fetchdotfiles daemon).

This would allow for automatic git syncing between dot files, and could be configured to occur with a cronjob, or upon boot, or manually.

Credentials would be HASHED and stored in a config file in /etc/fdfd, or could be used with a command such as `fdf sync ... ...`
