It should be .../Westgate/Tickets/Elements/ShowHistory directory and
file should be named after name of the callback you want to use. In
this case it's SkipTransaction.

Below see comments about your code.

Logic of the code is slightly wrong. It will work, but it doesn't cope
with multiple callbacks. You shouldn't set $$skip to 1. Use "return if
$$skip;" as first line in the <%INIT> block. This way you can avoid
conflicts with extensions that use this callback.

Also, condition looks too agressive, you skip status changes,
comments, custom field changes and many other things, but it's really
up to you what to do here.

Check that $m->request_path matches 'Display.html'. This way you can
have short history on ticket's primary page and full when History tab
is clicked.
