RFE: Update Image imports to support pillow

[paul@…]

Fedora Linux (and possibly other downstream distributions) are moving from the traditional python imaging library to a fork called "pillow" that is more maintained and will have python 3 compatibility. This move is largely backwards-compatible but one thing that is not fully compatible is the way the imports work.

Currently, the imports can look like:

import Image
import ImageFont
import ImageDraw
import ImageFilter

or:

from PIL import Image
from PIL import ImageFont
from PIL import ImageDraw
from PIL import ImageFilter

but pillow only supports the latter. If you could update captcha/image.py to use the latter format rather than the former then the code would support both libraries.

More details on this change can be found here: ​http://fedoraproject.org/wiki/Features/Pillow

Proposed Fedora patch

I ran into a similar issue with the ​th:OdtExportPlugin, and found that from PIL import Image was failing on Debian 6. Based on ​this SO reply, I went with the following solution:

try:
    from PIL import Image
except ImportError:
    import Image

See ​[th 12786]. I thought this might be of interest here.
