Woody + IE

[Christopher Oliver]

I also made a change to the Woody Button widget and woody-default.xsl to 
make it work on IE. Previously it generated a <button> element but 
apparently IE doesn't return the "value" attribute of <button> as a 
request parameter. So I changed it to simply create an <input 
type="submit"> instead. Please review this change and make corrections 
if necessary.

Regards,

Chris
