Beginning of code to handle subprojects. Also projects now are beginning tocarry project status information (such as total number of hours worked). Alot of UI improvements. Still rough, of course.
added the acs_user::get_by_username proc and the permanent switch to acs_user::delete that serves as a wrapper around the acs_user.delete plsql proc. Unfortunately that proc doesn't seem to work reliably
making the auth_authentication test case pass. Fixing a few bugs and adding some error handling to the authentication proc. Simon has added other test cases that have not been finished yet
defaulting username of site-wide-admin to email and making sure the stubbed ad_conn can handle multiple arguments (create-admin-2 bombed before this fix)
