Fix #52 IE8: inline style not working

In fact, it works fine in IE8 in  'IE8 Standards' mode. 
It doesn't work when either 'IE7 Standards' or Quirks modes is activated.

This PRs simply adds a test for inline style, and fixes the playground page to use 'IE8 Standards' mode by default in IE8. It also removes the useless `name=null` that were generated.
