Chrome and Moonlight, or how to deadlock a browser

It’s no secret that Moonlight works best on Firefox at the moment - it’s our baseline browser, after all - but we’ve had many requests to add Chrome support, and since it supports NPAPI just like all browsers out there, it should really work out of the box, requiring only some extra code to implement/hackify stuff that Chrome/WebKit doesn’t expose and that we need - basically, DOM support and some downloader tweaks.
