[ Unified UI ] Settings App Update & Refactoring

[Armored-Dragon]

The settings application(s) that exist presently in Overte are all Over-te place. There exist several separate QML based settings applications that each target one specific area of the overall settings of the application. Some users have also expressed frustration with the sometimes confusing layout. I have also had issues with trying to find a specific setting only to find I just can not see it because I am not in a specific view. This made walking though new users with specific settings very difficult.

Graphics Settings: https://github.com/overte-org/overte/blob/master/interface/resources/qml/hifi/dialogs/graphics/GraphicsSettings.qml
Controls: https://github.com/overte-org/overte/blob/808135b6c4a63c12f8dd35fc8aa9741a69ad3263/interface/resources/qml/hifi/tablet/ControllerSettings.qml
Audio: https://github.com/overte-org/overte/blob/808135b6c4a63c12f8dd35fc8aa9741a69ad3263/interface/resources/qml/hifi/audio/Audio.qml

These applications were also built at different times by different people under different design principles. These apps should be consolidated into a single cohesive application that neatly organizes all settings. Improvements must be made to the whole construction of the application UI so that future maintenance is quick and painless.
