Fix type pikcle->pickle in multiprocessing test
Fix pickling blueprints Change the string passed in the "name" section \ 
of the namedtuples in Blueprint to match the name of the Blueprint module \ 
attribute name. This allows blueprints to be pickled and unpickled, without \ 
errors, which is a requirment of running Sanic in multiprocessing mode in \ 
Windows. Added a test for pickling and unpickling blueprints Added a test for \ 
pickling and unpickling sanic itself Added a test for enabling multiprocessing \ 
on an app with a blueprint (only useful to catch this bug if the tests are run \ 
on Windows).
Fix document for logging
