Merge pull request from fperez/__IPYTHON__...

Merge pull request from fperez/__IPYTHON__ Switch to simple `__IPYTHON__` global to indicate an IPython Shell object has been created. Note that this does *not* try to track whether user code is being executed by ipython via %run, nor whether the Shell object itself is running an interactive event loop or not. So the answer for how people should query whether IPython objects are active is now simply ``` try: __IPYTHON__ except NameError: print 'not in IPython' ``` We do not attempt to track activity levels anymore, as we realized that logic was ultimately to brittle and error prone to be of any real use.
