2.5

Added WM Jobs manager
- WM can manage threaded jobs for you; just provide a couple
  of components to get it work:
  - customdata, free callback for it
  - timer step, notifier code
  - start callback, update callback
- Once started, each job runs an own timer, and will for
  every time step check necessary updates, or close the
  job when ready. 
- No drawing happens in jobs, that's for notifiers!
- Every job stores an owner pointer, and based on this owner
  it will prevent multiple jobs to enter the stack. 
  Instead it will re-use a running job, signal it to stop
  and allow caller to re-initialize it even.
- Check new wm_jobs.c for more explanation. Jobs API is still
  under construction. 
  Fun: BLI_addtail(&wm->jobs, steve); :)

Put Node shader previews back using wmJobs
- Preview calculating is now fully threaded (1 thread still)
- Thanks to new event system + notifiers, you can see 
  previews update even while dragging sliders!
- Currently it only starts when you change a node setting.

Warning: the thread render shares Node data, so don't delete
nodes while it renders! This topic is on the todo to make safe.

Also:
- bug in region initialize (do_versions) showed channel list in
  node editor wrong.
- flagged the channel list 'hidden' now, it was really in the
  way! This is for later to work on anyway. 
- recoded Render API callbacks so it gets handlers passed on, 
  no globals to use anymore, remember?
- previewrender code gets now so much nicer! Will remove a lot
  of stuff from code soon.
