Inspect webpack and similar bundles

[kassens]

The current detection is based on globally installed variables, like window.jQuery.some.version. This used to work pretty well, but these days more and more pages are switching to bundlers like webpack.

I think it might be possible to look at how webpack et al are working and inspecting the modules that are loaded from there.

"tree shaking" (dead code elimination) from rollup.js might also be interesting in this regard.
