Add user settings / preferences API endpoint

[dennispost]

Add an user settings / preferences endpoint to api, to make it possible to change user settings via authenticated api call.

Currently you get these settings object via socket message. But there is no way to change it via api or socket message.

[...]
"settings" : {
      "preferences" : {
        "newRoomNotification" : "door",
        "useEmojis" : true,
        "hideFlexTab" : false,
        "unreadRoomsMode" : false,
        "unreadAlert" : true,
        "convertAsciiEmoji" : true,
        "collapseMediaByDefault" : false,
        "saveMobileBandwidth" : true,
        "autoImageLoad" : true,
        "hideUsernames" : false,
        "highlights" : [

        ],
        "emailNotificationMode" : "disabled",
        "desktopNotificationDuration" : 0,
        "notificationsSoundVolume" : 100,
        "newMessageNotification" : "chime",
        "hideAvatars" : false,
        "hideRoles" : false,
        "viewMode" : 0,
        "desktopNotifications" : "all",
        "sendOnEnter" : "normal",
        "mobileNotifications" : "all"
      }
}

@dennispost you got an endpoint to both get and set settings. Check the new docs

@jgtoriginal sadly they're not user preferences, they're only the server's settings.

@graywolf336 nice, I happen to need some user preferences methods, which I'm about to code the next week. Will focus basically on name, email, avatar & password for now.
I usually go by the code conventions when it comes to customization, is this something that might help you guys?

@jgtoriginal Feel free to implement the user's preferences rest api and submit a pull request, we will review it and provide feedback. 👍
