Download button too small for some versions

[gourlaysama]

In the download page for Scala 2.11.0-M3, the name of the release does not fit inside the Download button.

(at least of Firefox)

Same for all versions that end with -Mx, -RCx or .final.

@Warry do you think you have time to fix that? Otherwise I'll do it, but it'll probably take me five times more time, given my css skills ^^

I guess maybe there could be some horizontal scrolling thing? (Not sure if that'd be too annoying– @Warry is definitely the guy with all the css and esp. animation sense.)

Thanks for the css-fu @adriaanm!
