[web2py] Re: Use bpython with web2py

[Arun K.Rajeevan]

In response to the events in which bpython isn't installed/crashed, my 
previous patch will revert back to ipython (if installed).
The attached patch will revert straight into plain python shell, instead of 
checking for ipython.

Apply, if others think, that's appropriate

Thanks, 
Arun
