Update dependency striptags to v3

[renovate]

This Pull Request updates dependency striptags from v2.2.1 to v3.1.1

Release Notes

v3.0.0

Completely rewritten from the ground up, using some of Node v4+ javascript features. Changes around the state machine aspect should mean an increase in speed.

Now features a streaming mode, where partial HTML can be pumped into a function and stripped HTML is returned.

No can do, my friend. striptags v3 is incompatible with uglifyjs-webpack-plugin. The uglifyjs-webpack-plugin team has fixed this, but they haven't released the fixes yet. Even then, the fixes will need to trickle down to webpack-stream, the package we use directly that has uglifyjs-webpack-plugin as a distant dependency.

My mistake. The fix has been released and webpack-stream is using it. I'll reopen the PR.
