Parsers.Config.readlink() - Fix typo
pynag.Parsers - New class: LivestatusQuery

This class is a convenience class meant to help
construct queries to mk-livestatus.
pynag.Parsers.Livesatus: add write(), raw_query()

This patch creates new general purpose methods
for talking to mk-livestatus.

write():
  Write a query directly to livestatus
raw_query():
  Easily construct a query and write directly to livestatus

Helps with issue #170
pynag.Parsers.Livestatus.query(): update docstring
pynag.Parsers.Livestatus.query() refactored

Rewrote almost all of query() using the new
LivestatusQuery helper class and raw_query() method.

This method is still a monster, but hopefully clearer
to read now and better documented.

Issue #130
Parsers.LivestatusQuery: Capitalize all constants.

Make all constants capitalized for pep8 compliance.
