Fixed pattern seach for goal subject.

Though doing it this way is a bit cumbersome; we should probably instead
alter the way goals are exported from cyphesis.
Fixed reference to connector.
Added comment about socket setting.
Don't truncate in lists.
Disable the use of EmberPagingSceneManager.

 - Create dummy implementations for the needed scene manager classes.
 - Use Ogre default scene manager or OctreeSceneManager if loaded.

Most of the changes are preliminary and not intended to stay like this.
The intention is to have something which works for now.
