Added member export
Start adding study
Small fixes
Study can be added manually and edited
Streamlined the installation controllers

Modules define {acl,roles,configuration}.config.php, which will be installed
when the install controller is called upon.
Subclasses of InstallController can declare preInstall and postInstall. Both
functions return void and allow for other installation actions to be taken.
