Subject: Added Image.GetCurrent() Previously the only way to get the current
 image was flaky and relyd on the image being assigned to a mesh.

try:
  me = Scene.GetCurrent().getAttiveObject().getData(mesh=1)
  image = me.faces[me.activeFace].image
except:
  image = None

...Can new be replaced by the following, and works even when there is no mesh.
image = Image.GetCurrent()

epydocs:
  Get the currently displayed Image from Blenders UV/Image window.
  When multiple images are displayed, the last active UV/Image windows image is used.
