Browse Source 
## Description of change

* Add a red `x` button to replace `Clear` button in binding tabs
(Buttons/Analog/Lights).
* Add a gray `x` button to replace `Clear` button in options tabs next
to input widgets
* Add helper for truncating text and adding ellipsis (...) to deal with
text overflow in tables.
* Reword some UI text for clarity
