Summary: Modify l-in-10 scripting->event application

New Features:

Bugs Fixed: LPP-3247

Technical Reviewer: ptw
QA Reviewer: (pending)
Doc Reviewer: (pending)

Documentation:
The existing app doesn't work as intended because of an initialization 
issue. The onwidth() event is fired during initialization and this turns 
the view blue. The intent of the demo is to show an event being fired when 
the user clicks on a button.

My first thought was to make sure the object was fully initialized before 
enabling the onwidth event. The problem is that it will make the app look 
more complicated. I took an easier route and changed the onwidth() method 
to only turn the view red if the size changes from the initial value. There 
are lots of ways to solve this issue and the simplest is to hard-wire the 
initial width into a conditional. I changed

     <handler name="onwidth" >
       this.setBGColor(0xFF0000);
     </handler>

to

     <handler name="onwidth" >
       if (this.getWidth() != 100)
         this.setBGColor(0xFF0000);
     </handler>

This change requires no explanation to the reader.
