Merge pull request #1 from cptvitamin/master

Clarifications in README and changes to absolute base test (but i will add a warning that the base is only useful as long as github and i don't break it)

Made links in the README live
offline HTML readme

Added an HTML readme that duplicates the .md one, for use when you
download everything and want it to run offline.

15 of the tests actually provide 3 different pass conditions for 3
different results, using the same test.

Added descriptions to pass pages that didn't have them
Fixed a b0rken link

things are generally called ...description.html not desc.html
