Add crypto polyfills back

[AaronDewes]

Fixes #101 (comment)

Please test this before merging, I haven't tested it myself yet

[timvisee]

This doesn't seem to fix it.

Now I'm seeing the following browser console error:

./node_modules/asmcrypto.js/asmcrypto.all.es8.js
Module build failed (from (webpack)-unassert-loader/index.js):

I just confirmed that 64644b5 is indeed the first bad commit.

Can you check if this version works? It did not throw any errors for me locally.

Still errors, sadly. This happens when I start the upload:

I'm testing locally with npm install && npm start on an HTTP domain. Do you use a different testing environment?

I'm sorry I can't dive into this further myself, I'm quite limited on time these days.

[AaronDewes]

I'm just doing npm install && npm start, but on localhost. A polyfill is only needed for HTTP domains that are not localhost. I will try with another domain later.

I've reverted the changes from #101, on which this PR builds further.

Once we get this PR properly implemented, I'm very happy to put it all back in. The conflicts currently showing are due to the reverted commits.

Please see #101 (comment).
