Beta wallpaper revision

[Emily Dirsh]

I know it's a bit down-to-the-wire, but I (finally! ;)) finished a new
revision of the beta wallpaper. It's up on the wiki now here:
https://fedoraproject.org/wiki/File:F14-wallpaper-remix-em-light-rev1.png

I replaced the light spots/lens flare with a light streak/aurora effect.

I don't have the source file uploaded just yet - it's huge! - but I'm
working on it and I'll post a link on the wiki ASAP.

See what you think!
