[arch-dev-public] Update flashplugin to 9.0.64.0?

I have been using flashplugin 9.0.64.0 (which is the latest beta for the next flash 9 update) for some time. I didn't have more stability problems than with our current version (rather less) and it has support for fullscreen mode (which is awesome for youtube). I am proposing to update it in testing (or extra) and use that beta instead of the latest stable. Opinions?
