Campbell Barton 8a83aff9f5 [#18678] Swizzle properties for Mathutils.Vector ...

patch from Alex Fraser (z0r)

eg.
  - vec.xyz = vec.zyx
  - vec.xy = vec.zw
  - vec.xxy = vec.wzz
  - vec.yzyz = vec.yxyx

See http://en.wikipedia.org/wiki/Swizzling_(computer_graphics)

made some minor modifications to this patch.

tested access times and adding 336 attributes to vectors doesn't make a noticeable differences to speed of existing axis attributes (x,y,z,w) - thanks to python dict lookups.
