General particle bug fixes + few small goodies

The goodies:
* Curves can be used as normal dynamic effectors too with 
  the new "curve" field shape.
* Group visualization has optional duplication counts for
  each object in the specified group.
* Object & group visualizations, which are done without
  taking the dupliobject's global position into account
  (unless the whole group is used). This is much nicer than
  the previous behavior, but I added a "Use Global Location"
  option for those who want to use it the old way.
* The active particle system's particles are now drawn a 
  with theme coloured outline instead of pure white.
* Added object aligned velocity factors (buttons categorized
  and re-organized too).

Bug fixes:
* Absorption didn't work as the ui toggle button was forgotten.
* Some other force field ui tweaks.
* Crash after adding children and changing trails count.
* Display types "cross" and "axis" crashed.
* Particles weren't drawn with correct coloring.
* Billboards didn't update properly in viewport to camera
  location changes.
* Particle rotation wasn't recreated correctly from point cache.
* Changing particles amount crashed sometimes.
* Some files with child hair crashed on loading.
* Compiler warning fixes.
* Adding boids crashed on frame 1;
