vout: update priority rules to account for SPU blending

This moves Direct3D on Windows (with no effects on actual order) and
OpenGL on Linux/BSD (now exceeding XVideo thanks shaders and blending).

It remains to be decided whether OpenGL should be increased on Windows;
in principles, it should have a higher priority than D2D and DDraw.

+The priorities ranges are as follows since December 2014:
 
  - less than  20: console (text)
  - less than  50: plain frame buffers
  - less than 100: no embedded windowing
  - less than 150: SW scaling
  - less than 200: SW chroma conversion

  - rest: good stuff :-)
 
 No more than one plugin with a given non-zero riority.
