Takashi and I chatted about bug 305885, and Takashi told me that 
being able to remove FontFaceRule from CSSFontSelecter would be useful.

Takashi-san, let me know if you like to this landed.

Interesting approach. I like it.

[tasak, 2013-11-18 08:21:17]

lgtm.

I like it, however I'm not familiar with FontSelector-related codes.

So dglazkov, would you review this CL?
