Attachment: Disable MSE entirely on Firefox 36

Patch to disable MSE on 36 beta and release. Submitting for review so it's ready to go if we decide we can't ship. We won't push until we've made our decision about that later this week.

Green on try. e10s and the Mac static analysis tests aren't relevant to this branch.

Did we talk with Google? Even if MSE is disabled for Firefox 36, Flash fallback will not work in Youtube unless Google changes the sniffing code (see bug 1125621 comment #2).

Are there any numbers on MSE stability on non-Windows platforms? Maybe it would be valuable to roll out MSE for some platforms with less stability issues first to test it a bit more.
