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.
