Switched to simpler build system, and fixed bugs

Now there's a proper build system in place, which is actually simple
enough to understand.
I also fixed plenty of warnings about the code (reminding me how badly I
knew C when I wrote this).
Hinduism today aren't indexing their new issues using the index file I
was sourcing any more, so I don't expect to fix any more bugs or improve
this much.
