Unhide files.

Ironically, this is done by removing the dots from the filenames.
Add license file.

Please contact me if you wish to relicense any of the code in this

Symlink script to automate linking dotfiles.

I was originally going to use the Bash script in
<https://github.com/michaeljsmalley/dotfiles> as a template, but I
eventually decided to write a Python script from scratch. This is mainly
because I did not want to license this under the GPL3, but also because
I like Python and felt a bit rusty with using the os and shutil
modules.
Add README.
Use symlinks.

The previous incarnation of this used a Git repository in the home directory,
which is super confusing. Despite the fact that several people on the Internet
think that this is a good idea, I advise you never to do this.
