Subject: Create some basic infrastructure:   * item model (contains basic item
 info, similar to the gx version)   * module model (has info about each module
 and which version of it is installed)   * added a very basic unit test to
 verify that we can create an instance of item   * Updated our test controller
 to require a unit_test db config and     call core::install if it hasn't been
 done already.

New pattern:
  * core/helpers/core_installer.php creates core_installer helper.
    When we install a new module you call xxx_installer::install(),
    and when you want it to go away, you do xxx_installer::uninstall()
