Improper query string breaks everything

[Stuart-Wilcox]

The malformatted query string /people?location (with no =val) is a malformatted query string, but causes an index out of bounds error since it is expected to be a proper query string. Check the stack trace:

Traceback (most recent call last):
  File "..\site-packages\servepy.py", line 30, in handle
    http = _Http(self.data, self.server)
  File "..\site-packages\servepy.py", line 572, in __init__
    self.request = Request(server.app, complete_url, protocol, method, headers, body=body, params=dict(), cookies=None, baseUrl=None)
  File "..\site-packages\servepy.py", line 596, in __init__
    self.query[pair[0]]=pair[1]
