Scripting service to use blitz gateway

[wmoore]

If we can use the blitz gateway in the scripting service, then all Python API users can start in the same place - docs, API learning etc and this functionality is available to Script writers.

Need to be able to create a blitz wrapper from the 'client' object provided by the scripting service.

client = script.client("Script.py",)

First attempt:

>>> import omero
>>> c = omero.client("localhost")
>>> s = c.createSession("root", "omero")

>>> import omero.gateway
>>> from omero import client_wrapper
>>> conn = client_wrapper(client_obj=c)
Traceback (most recent call last):
