While trying to dig through and understand the goings on of Data Binding I started commenting the code in TextObservableValue for my own benefit and figured I'd give it back in case it could be used.  I made 2 small code changes.  

* I renamed the parameter and instance variable that were named "updatePolicy" to "updateEventType".  The reason for this was that initially because of the name "updatePolicy" I had assumed that it was accepting either DataBindingContext.TIME_EARLY or DataBindingContext.TIME_LATE.  The confusion came when the code was then treating it as an SWT event type.
* Added checks to the constructor that validated the inputs mostly out of habit.  Since I touched it by changing the parameter name I figured I should validate it as well.

I'll attach the patch and a JUnit.  All existing tests in TextControlScenario still pass.
