Added TLS mode support which can be enabled by the checkbox in Settings -> General. (Thanks to JReming85 for the suggestion).

This version will create a certificates folder in your xTeVe config directory.
Before enabling TLS mode, you should put a self-signed certificate and it's private key in there, for example:

/home/username/.xteve/certificates/xteve.crt
/home/username/.xteve/certificates/xteve.key

You can either generate your own or download a 'dummy' certificate and it's key from this repository.

❗ Certificate from this repository will only allow TLS mode to start up but not to actually establish a secure connections.
For truly working HTTPS, you should generate it by yourself and also add self-signed root CA to client-side certificate storage (where the web browser, Plex etc. is).
