We can now retrieve files from the git repository without passing them
through `asciidoc`. This allows us to retrieve images, etc..

- Attempt to implement image rendering.

Added -d book to the asciidoc call.

The contents of the website will be stored in doc/, because they are actually
documentation.

Added needed images. Update of Git_Access.txt, demo page.

Added templates/page_modules.php, which show the very simple approach to
 content management.

Added header/footer

Fix stylesheet, miam miam.

Corrected behavior to show the file. Remove header and footer. Needs to be
added to a local .css file.

Git_Access: add information about how to autoreconf --install.
