I came across this while working on overviewer#42 but it seemed like its own problem, worthy of its own PR.

9 days ago, [werkzeug was updated](https://github.com/pallets/werkzeug/releases/tag/1.0.0)

The changelog contains this:

> Remove most top-level attributes provided by the werkzeug module in favor of direct imports. For example, instead of import werkzeug; werkzeug.url_quote, do from werkzeug.urls import url_quote. Install version 0.16 first to see deprecation warnings while upgrading. #2, #1640

So I updated the components that import from werkzeug to versions that have the imports fixed.
