Adding support for new generation 'framed' popups. This patch includes numerous improvements to the main popups, including the addition of autoSizing, panIntoView, and full support for overflow:auto of the contents div. Thanks go out to the CloudAmber folks, to Pierre in la belle France, to the guys at TOPP and of course, to senior cr5 for his patience and help in the last and final stretch. this is a huge improvement in the popup arena and couldn't have been done without the broad help of everyone out there in the community. Thank you everyone for making this possible. Big step for OpenLayers. (Closes #926)
