First draft of a new AsciiDoc-based index page.

Instead of having a separate download page, it could be nice to have
it immediately available when visiting the web site. Additional links
can be added for more specific subpages.

Also there's no custom styling yet.
Add a Makefile to generate the web pages.
index: More fleshed out Introduction section
Add the about page.
Move Download to its own page again.

The front page was a bit too cluttered with it there.
Change 'open source' to 'free content'.

Freedoom has always established itself as free software, the change to
open source was sudden and made its own name seemingly contradictory.

Freedoom is not source code nor software, however, so call it 'free
content'.
Reword twenty years into "over the decades"

Avoids the page going out of date based solely on how increasingly far
in the past 1993 was.
Custom theming for the web site.

Uses the old layout pretty much, and .forkme.txt is just part of the
layout conf now.
Add an em-dash in the page title
Separate out AsciiDoc options and use dos2unix
Add a bunch of links to the sidebar
Add project news to the index page
Add notice about the web pages being machine-generated
Add the screenshots page
Download: Change PrBoom to PrBoom+

I had reservations about it because I think its web site makes it even
harder to find a download than the original project, but there's
hardly any reason to use the original over this fork anyway. Plus,
being the last choice listed on the page hopefully avoids new users
from being totally confused.
remove trailing whitespace cause it's a jerk
Generate HTML version of the site
