[Laszlo-dev] Snippets make 2 requests when font tag is present

[Henry Minsky]

I'm doing some testing, and it looks like this hack of using the
 ImportAssets2 inside of a snippet for font loading may no longer be
necessary, at least for Flash player 10  ( I am running the debug flash 10
player), and hopefully same goes for Flash player 9 .
