update NetwokStream to support wss SSL valid cert

[bukira]

change "false" to "true" for isValidSSLCertificate() in NetworkStream
This allows NetworkStream to work with WSS web sockets and valid SSL certs.
Apple automatically checks certs so no manual check is required

This PR creates a new file. Please change file in Sources/Starscream/

[bukira]

I have no idea how to do that, I tried with the PullRequest which obviously didn't work, but as you can see from the commit its only a one word change, anyone can make the change

[fassko]

@bukira you need to edit existing file in Sources/Starscream/NetworkStream.swift

Right now you have added that file in home directory.

@fassko

Yes but I have no idea how to do that, I gave it a go and obviously it wasn't right, as I have no idea how to do what your asking I can't do.

All I request is 1 word change from "false" to "true"

[fassko]

@bukira you need to clone xcode-10 branch and edit file Sources/Starscream/NetworkStream.swift

[bukira]

Thats exactly what I did

[fassko]

If you check files changed then you can see that NetworkStream.swift has moved to home dir

See PR #653. It refactored all this logic and has certificate pinning support.
