I've got the beginnings of the Rbac functionality going. Still testing. The site is broken in this commit.
I've got the database installing the new tables regarding access control, along with default data inserts for testing.

Also cleaned up the installation process by removing fields from the 'Venue Info' page. Users can enter that info after installation.
Major installation schema, default installation, and dbCreate changes.

* Restructured the installation db schema so it's easier to list database table KEY's.
* Updated the dbCreateTable doc block example to reflect changes
* Updated install_alpha.php to reflect changes
* Added the db tables for phprbac (to their specifications) to default installation routine
Started integrating PhpRbac for access control.
Fixed an issue where the zones for the main domain (mysite.com/www.mysite.com) were loading incorrectly.

Now the main domain zone folder name must not include 'www.', i.e. the mysite.com zone will be loaded when a user navigates to mysite.com AND www.mysite.com.
Getting code ready for validation work. Fixed an issue connected to 'links' table changes.
Login and Logout session management is now functional.
