[Catalyst] Patch for HTML::Widget to ease addition of javascript events

[Andreas Marienborg]

The patch is against trunk at oook.de.

It adds an accessor to ::Elements and sub-classes called events().

In addition every class has the events it supports added to it, so  
you cannot add events that does not exist for a particular element.  
Any others are silently ignored for now.
