Moved loading and initializing of DCB to a helper; updated setting of DCB environment and Drupal core version for DCB 3 API.

Changed assembleComponentList() to return component list to the task, and associated methods to use it.

Changed Hooks generator to take a parameter of hook names, and pass requested HookImplementation components all their necessary hook data.

Fixed assembleComponentList() merging identical requested components, causing errors in their data array.
