/* event_attach() takes care of attaching event handlers (functions) to events.
* this simplifies the process of attaching multiple handlers to a single event
*
* NOTE: the onload stack is executed in a LIFO manner to mimic
*       IE's window.attachEvent function. However, Opera also has its own
*       window.attachEvent function which executes the onload stack in a
*       FIFO manner. FIFO is better, but IE has a larger user base, so
*       LIFO is the way we go.
