Remove Flash fallback and come up with workaround for wav only in IE

[dapphp]

The upcoming 4.0 release is removing Flash audio fallback. Since no present versions of Internet Explorer support WAV in HTML5 audio and most people probably won't have LAME installed or know how to set it up, it's probably necessary to come up with an alternative for IE.

One possibility is to use the existing IE detection in securimage.js to go old school and drop an tag in the DOM for IE to play when the button is pressed.
