elevate stack block id and frame info into thread

Browse source 
- Add pointer member to thread. This is the current executing block.
- Add stackFrame member to thread. This is the current frame
  information like procedure parameters.

This is a step potentially towards stack-less threads. With further
modifications we could have stack and stackFrames be null if a script
does not call a procedure.
