moved all globals out of sendMementoHeaders and into ArticleViewHeader hook, replacing globals with static memeber variables, which isn't much better, but at least it gives me one place to try and fix the global problem
fixed bug in Special:SpecialPages caused by global reorganization
Moved todo-list.txt to TODO to be compliant with GNU standards, imported integration tests from my machine: which are, unfortunately, still tied to a specific installation of Mediawiki, but the data has been separated from the tests, meaning that data files can be created for any Mediawiki installation
Integrated integration tests with the Makefile framework; also documented how to use Makefile inside a README, to conform with GNU standards.
Added complete flow integration test to the mix, and updated README
