First import of the basis of the 0.2 release of provision. This version has a much cleaner api, through the dynamic inclusion of <command>.provision.inc files , which any module can overload. Each of these files has the exact same structure, and thus it is much clearer what happens when, and much much simpler to document / extend. I also removed all the drupal dependencies i could find, in preperation for moving to a version agnostic drush, for all buy provision_drupal (which is going to be spun off into a different project). This also includes a working update command, and keeps track of the modules installed on a site after every verify / upgrade process. This information is not being tracked in hosting, yet
