Removed event object.

It didn't have any real data in it.

Not sure if this is the right way to do it.  Prob
should just have a single event for user control
and send the detail of the event as the object.  But
I'm not sure.
Added in a .ruby-version for fun.

This is more of a local development need, but others
could benefit from it as well if we ever use ruby
for something.
