HTTP to HTTPS

[CharlieBrownCharacter]

Steam now requires that all requests made to their API endpoint needs to be made via HTTPS. I had a lot of issues by not having making calls to HTTPS. I think a change is needed in all files and remove the option of "Is using HTTPS" in the config file

The option in the config doesn't change the requests to steam but if your callback is called via https or http.
And this is the only point where I see a http request https://github.com/invisnik/laravel-steam-auth/blob/master/src/SteamAuth.php#L46 feel free to fix it. 😉 The parser was fixed in #77
