Enable import/export from git repo following http://traviscline.com/blog/2010/04/27/using-hg-git-to-work-in-git-and-push-to-hg/.
Changed the way processors are loaded.

You can specify API(locale=...) as

* a class
* a class name as string (e.g. 'mymodule.processor.ProcessorClass')
* an instance

If not specified, the first one of amazonproduct.processors.objectify.Processor, amazonproduct.processors.etree.Processor or amazonproduct.processors.minidom.Processor successfully imported is used. Note that the etree processor will try to import a number of possible implementations before giving up.
Cleaned up setup.py
