Stable vs Dev version, document image enhancement

[Parand Darugar]

Hi Tony,

Installation steps:

This is on OS X 10.8.2, Python 2.7.2:

- I setup a virtualenv and activated that virtual env.
- I cloned the scikit-image git repository
- I installed:

$ python ./setup.py install
...
Installed 
/Users/parand/Projects/Receipts/pyenv/lib/python2.7/site-packages/scikit_image-0.8dev-py2.7-macosx-10.8-intel.egg
Processing dependencies for scikit-image==0.8dev
Finished processing dependencies for scikit-image==0.8dev

$ python

>>> import skimage
>>> skimage.__version__
'0.8dev'
