Update website to reflect Opera native support

Hello, since Opera natively supports rounded corners, CurvyCorners website 
should reflects this change in various pages:

1) home page (http://www.curvycorners.net/):

"CurvyCorners only does its magic on browsers that don't have CSS3 
border-radius support, namely IE and Opera."

now there's only IE left :)

2) instructions (http://www.curvycorners.net/instructions/):

"Using CurvyCorners the new way — using CSS" section, sample code is 
currently:
.rounded {
  -moz-border-radius:3ex;
  -webkit-border-radius:3ex;
}

"border-radius" should be added as well

3) I presume there are some other parts of the website to update as well ;)

Regards
