CB

Implement installer check to the system plugin. It should make sure the currently being installed version of CB is not less than the currently installed version. This will stop 1.x from overriding 2.x and causing issues.

Trigger: onExtensionBeforeInstall
Variables: array( 'method' => 'install', 'type' => $type, 'manifest' => $this->manifest, 'extension' => 0 )

Trigger: onExtensionBeforeUpdate
Variables: array( 'type' => $type, 'manifest' => $this->manifest )

Probably need to use the update trigger instead of install trigger as believe install only fires for new installs, which we don't need to bother checking.
