Removed the hack from goog.ui.TextArea which set the contained empty textarea's value to ' ' to prevent its height from becoming zero. I didn't manage to reproduce the zero height bug in Firefox, Chrome and Opera. I couldn't test IE.
As a result the CHANGE event isn't swallowed when the textarea is cleared then unfocused.
Fixes issue 503.
