Automatically detect information from Device

[ranyefet]

Hi,

Thanks for the great middleware, already using it in development! I've noticed the events I'm sending missing properties that are available when using iOS API. https://mixpanel.com/help/questions/articles/what-properties-do-mixpanels-libraries-store-by-default

Things like: App Release ($app_release) - General build of this app. App Version ($app_version) - Full detail of this app build. Carrier ($carrier) - Wireless carrier of the device owner. iOS Ifa ($ios_ifa) - iOS identifier (IDFA or IDFV, depending on which is available to the app). iOS Version ($os_version) - Current version of iOS on the device. Manufacturer ($manufacturer) - Always Apple (so far...). Lib Version ($lib_version) - Mixpanel library used to send this data. Model ($model) - Device model ID, in format "iPad 3,4". Full list here. Operating System ($os) - "iPhone OS" (outdated naming convention). Screen Height ($screen_height) - Height, in pixels, of the device screen. Screen Width ($screen_width) - Width, in pixels, of the device screen. Wifi ($wifi) - Set to true if Wifi is connected, false if not.

How hard is to integrate it into this middleware?
