Fix bugs related to task_includes and dep chain inheritance

Browse source 
* Fix the way task_include fields were created and copied
* Have blocks get_dep_chain() look at task_include's blocks for proper
  dep chain inheritance
* Fix the way task_include fields are copied to prevent a recursive
  degradation
