Fix left-side navigation for top-level pages

Fix left-side navigation for top-level pages

And don't break presubmit!
Basically, the change I put in previously that kind of fixed extensions redirects
actually meant presubmit would fail.
So I've gone and put in a real fix.

I also updated the redirects.json files in these GitHub repos for this to work: devtools, multi-device, and store.

Thanks, Ben, for your help.

Ben,

I need an lgtm from a native-client owner.

Thanks,

Brad could you please take a look for the NaCl doc change? I think it's trivial,
but didn't want to TBR here

This is still failing without a valid owner-- brad, are you also
bradnelson@chromium.org? I don't see a bradn in the OWNERS file.

I'll check with binji to see if he can lgtm.
