#5 Add textbox onblur / onchange functionality

[Nicholas Neuberger]

Add the functionality to the API that fires onblur /
onchange javascript when entering into a text box or
html control. This should adhere to HTML specifications.

Plus, if possible, add into the API, the ability to
automatically call these methods. This eliminates the
need to call blur() and onchange() methods for each
data entry field. Possible on the setValue() method,
both will be called depending on a boolean
user-selectable field.

Also, add the proper junit test cases as examples and
tests to perform the functionality.
