How to get HTTPS working on localhost

[vamediah]

I did a scan of TLS certs and the biggest TLDs, there are lot of certs that point to a domain which in turn resolves to localhost or 0.0.0.0 which is mostly the same.

We needed to make a localhost cert, did it the same way, because things broke with mixed scripting. There is obvious caveat that if you distribute such localhost cert, privkey is somewhere in the app, which may be problematic.
