CI build failed because of some random lint errors in files that were not even affected by this PR, looking into this:

pinging @jkillian: it seems that tslint@next has a peer dependency >=1.7.3 || >=1.7.0-dev.20151003 || >=1.8.0-dev which no longer works after version of TypeScript nightly builds was bumped up to 1.9...

Thanks for the heads-up @vladima. I'll check to see that things are working with TS 1.9 nightlies and bump that dependency.

@vladima Just published a new next release on NPM, hopefully that should fix up the issue here

Thanks @jkillian!

@vladima I requested a re-run on Travis.

Fix looks good to me.

pinging @mhegazy should it also go to 1.8?

We will need to port this to 1.8.
