openlmi-tools on Windows

[Remi Chateauneu]

The Python client module openlmi-tools works on Windows 7.

The only thing to do is that it needs the module readline which is 
available on Linux only. The fix is to add in the currency directory, a 
file named readline.py (Because lmi-shell imports it), whose content is:

def set_completer(x):
	return

It would be nice to make this import conditional.

Thanks.
