Wrong URL has strange error message.

I fat fingered the URL parameter for the Sugarcrm construct and it was causing a strange error, namely:

Traceback (most recent call last):
File "gic.py", line 11, in
conn = sugarcrm.Sugarcrm(url, username, password)
File "/usr/local/lib/python2.7/dist-packages/sugarcrm/sugarcrm.py", line 42, in init
self._login(username, password)
File "/usr/local/lib/python2.7/dist-packages/sugarcrm/sugarcrm.py", line 125, in _login
x = self._sendRequest('login', args)
File "/usr/local/lib/python2.7/dist-packages/sugarcrm/sugarcrm.py", line 106, in _sendRequest
result = json.loads(response)
File "/usr/lib/python2.7/json/init.py", line 326, in loads
return _default_decoder.decode(s)
File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/usr/lib/python2.7/json/decoder.py", line 384, in raw_decode
raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded

When I finally figured out that I had erroneously set my URL, I was able to get things working as advertised. I think it'd be nice if there was a ConnectionError or something more descriptive.
