WTFramework 0.4.x direction

[David Lai]

Since we've been doing a lot more unicode testing here are Wiredrive.  We had to make significant changes to the framework to use unicode in all the places using strings.

Currently in the 0.4.0 revision, I've converted all the strings to unicode. The next steps from there is to start wrapping some of the data types and method calls to use __future__.  This will hopefully make the library forward compatible with Python 3.
