thermostat version 1.1.0 has been released!

Thermostat.rb is an attempt to build an easy to use ruby api around
the web services provided by the Proliphix line of network
thermostats. Their API is documented at
http://www.proliphix.com/Documentation.aspx.

The code is tested on the NT20e unit, which is what I own. It should
react that same across all their network accessible units.

Changes:

### 1.1.0 2010-03-10
* relatively complete unit test coverage
* add a simulation mode to the network layer so it's easier to test
* include usage methods in the main thermostat object
