automatically set minor version number in setup.py

Setup the minor version number in setup.py with jenkins

put one setup to create build.info

echo $BUILD_NUMBER > build.info

add build.info in setup.py

def __path(filename):
    return os.path.join(os.path.dirname(__file__),
                        filename)

build = 0

if os.path.exists(__path('build.info')):
    build = open(__path('build.info')).read().strip()

version= '0.6.{}'.format(build)
