Update to Browserify@8.0.2

* Rebases the two path fixes onto 8.0.2
* Waiting on smrq/tsify#25 otherwise npm will complain about the peerDep with karma-browserify
* All passing though: https://travis-ci.org/Nikku/karma-browserify/builds/45268310
* Closes Nikku/karma-browserify#74

This should be pushed as a `local-fix-8` branch instead of merging and then karma-browserify should be updated. Otherwise people are just automatically updated to browserify@8 on existing versions without the ability to pin to a past karma-browserify version if they had an issue.
