Added ruby and ruby-related files, as well as files used during build.

These files include scripts for building the website, as well as extra
functionality for the users of the website. The Gemfile also helps
ensure the necessary gems are installed.

In addition, scss files help with making CSS easier to organize. Though
the full power of Sass has not yet been leveraged by generalizing CSS
definitions or using other available functionality.

Added common project-description files.

These include copyright and licensing information as well as
instruction on how to setup a working installation.

The COPYRIGHT file describes the licensing of various components of the
repository. Images and media should be useable outside the scope of
forks, thus, they typically are licensed under a CC license of some
sort.

Unfortunately, licensing is a complex topic. There may have to be future
changes to account for situations I have not considered.
