Added warning when no HTTPS during register.

We already had a patch to warn users they need HTTPS when they login.
This was not working for the register form.

- Added a warning during the submit of the register form.
- Changed the check to see if `crypto.subtle` is defined or not.
- Removed the `webpack.config.js` patch, since this now is in upstream.
- Updated README.md shields and small comment regarding how to create
  the patch because of changes to the submodule.

 This is a repository to store the builds of the [Bitwarden web vault](https://github.com/bitwarden/web) with the patches to make it work with [bitwarden_rs](https://github.com/dani-garcia/bitwarden_rs)
 
+To create a patch you need to modify the original sources from [Bitwarden web vault](https://github.com/bitwarden/web) and execute:
+
+```bash
+git diff --submodule=diff
+```
+
+This is needed because there are patches within the jslib submodule which with a default `git diff` are not shown.
+
+For more information see: [Install the web-vault](https://github.com/dani-garcia/bitwarden_rs/wiki/Building-binary#install-the-web-vault)
+
 The builds are available in the [releases page](https://github.com/dani-garcia/bw_web_builds/releases), and can be replicated with the scripts in this repo.
 
 _*Note, that this project is not associated with the [Bitwarden](https://bitwarden.com/) project nor 8bit Solutions LLC._
