Svav/make python hub

Adding a new recipe to enabled python on the target. 
The recipe is based on the description from this page: 
http://www.trevorbowen.com/2013/10/07/cross-compiling-python-2-7-5-for-embedded-linux/ 
 And I have used the patch he refers as the basis, but it has been modified slightly. 

I have tested the build on a RaspberryPI running: 
python /usr/lib/python-2.7/test/test___all__.py
Please change all library dependencies to be listed in lib* format.

Fx. instead of all the readline dependencies used you should be able to use just 'libreadline'.  If this is not true, it is likely a bug in the readline recipe, and should be fixed there.

This is the standard method for defining library dependencies, and if followed, should make it easier to figure out how to add a dependency towards a specific library (ie. not needing to know details about the packaging structure use by the recipe building that library).
