Summary:                    add python 3 support to redland-bindings
Description: 
The python community is working its way to transitioning to a new incompatible
version of the python language. 

It would be really nice if redland-bindings supported python 3.

Steps to Reproduce: 
./configure --with-python=python3.3

Redland build summary:
  Redland:              1.0.16
  Language APIs built:   



Additional Information: 
With this patch the tests in python/redlandtest.py and python/test/test.py seem
to run under both python 2.7.5 and python 3.3.2.

There's some messiness introduced by this patch because I tried to keep both
python2 and python3 support.

To keep the same behavior print statements/functions have to be a single string
wrapped in () like:

print("a %s" % (var,))

print "a", var or print("a",var)

wont work the same on both versions.

The default string type changed to unicode which led to some tricks to keep the
behaviors of all the unicode casting that RDF.py was doing acting the same.

I also tweaked the python tests in configure.ac to work with both 2.7 and 3.3

To get the patch I ran the RDF.py through 2to3 and then undid some of the
unicode -> str changes.
