stylesheet@2x.css does not work on AppEngine

[jeremi]

With the new version of sproutcore 1.5.pre, there is a new stylesheet that ends with @2x.css.
When trying to upload an application to Appengine, the uploader list errors for all the files that contain the @ like this:

2011-03-13 13:55:45,202 ERROR appcfg.py:1517 Invalid character in filename: static/as/en/fd7ad64a4bc12493f2d0417a7bd5af070c0469ac/stylesheet@2x.css

Could it be possible to remove the @ from the filename or allow to rename it ?

Problems loading the @2x.css also happen for me in other environments. I see it even when I run with sc-server (even though sometimes several days go by with it loading just fine).

Also, this is not limited to iPhones, but any device with a high-DPI screen, including some Android phones.

@joubertnel, do you believe this is related to the @ symbol as well?

We still need to fix the underlying issue, but @2x files will no longer be created unless explicitly desired.
