Added Queryvars which is a template allowing redirection or actions triggered by a query variable or pretty url.
Added an AddActivationAction() method to Plugin class, which allows modules to hook into the activation event.
Added a feature to show the unexpected output of a plugin during activation by capturing the output to a transient, then sending that output to an admin notice.
During troubleshooting of a '1 character of unexpected output' error, i did a regex search and replace of any spaces that appeared before <?php. This has the potential to cause formatting problems, but i did not detect any
fixed inconsistent version retrieval so now versioning is done by setting the WordPress information header, not by using the Plugin->setVersion method.
Added a templates folder so we can hold the templates required by the Queryvars module.
Merge branch 'module-queryvars' into develop
