Fix doc format, add in makefile for docs

OK, first up, SOMEBODY *cough*analphabet*cough* screwed up the docs
by making them all use the wrong heading level. Not cool, guy. I
had to change them so they would compile right.

But anyway, now the docs will build into sexy-looking HTML and will
shortly be hosted on marktraceur.info.

Fixed the makefile to work properly.

Run:
 * `make clean` for removing old doc-build(s)
 * `make docs` for running new doc-build(s)
