HSC-1010: support WebSocket over TLS

[julbra]

Unfortunately with this it now doesn't work through gulp because of the port. Trying to get gulp with browser-sync to proxy WS requests took me a whole day and I failed because of various bugs.
I tried with http-proxy-middleware which was the most promising library but it failed
See mainly: chimurai/http-proxy-middleware#15

I think you need to check the port - if the default of 80 or 443 is used, I think port will be empty, so you will end up adding a colon into the URL at the end - think you need to check if port is non-empty and only add if that is true.

i.e. if the URL is https://stackato.helion.space

the port will be empty, so I think, as is, the URL you will derive for web sockets would be:

wss://stackato.helion.space : /pp/v1

@nwmac I'm pretty sure $location does the right thing and returns the port in all scenarios.
Yep port 80 is actually the example in the docs:

// given URL http://example.com/#/some/path?foo=bar&baz=xoxo
var port = $location.port();
// => 80

thanks for checking - LGTM
