Clean up "Hacked" CSS

There was no need to over complicate the 'hacked' CSS to use the
bounce.js library.

By simply hiding the div to begin, then showing it on mouse over you
will get the desired effect without the "jitter" that is a pain in the
video!

Timing, etc. can be adjusted as needed to get the desired effect, but this leaves the CSS far cleaner which is a definite plus! 
overflow: hidden makes the 'bounceOut' animation looks worse, but is required by others 

This is a terrible solution to the issue that some animations may require the parent container to have special conditions. A better solution may be to define a 3rd class in each animation where the container can be given properties, but for the presets which I added this suffices.
