This is awesome! Goodbye to extra e.get() boilerplate.

PSA: nsFrameList now supports range-based for loop

[Xidorn Quan]

I've landed bug 1143513
https://bugzilla.mozilla.org/show_bug.cgi?id=1143513 which enables using
range-based for loop on nsFrameList. Now, when you want to iterate
nsFrameList, you no longer need nsFrameList::Enumerator. Just write:

for (nsIFrame* frame : mFrames) { }

Also, with the reverse iterator landed (bug 1127044
https://bugzilla.mozilla.org/show_bug.cgi?id=1127044) before, if you need
to reversely iterate the frame list, the Reversed function is also usable
here:

for (nsIFrame* frame : Reversed(mFrames)) { }
