UI Builder V1.0

This can eventually be expanded to all of Edit, for now, starting
with Particles Only.

This is created for the sole purpose of streamliming the bridge, and to simplify
the logic between an inputfield in WebView and Entities in High Fidelity.

We also do not need anything as heavy as jquery or any other platform,
as we are mostly only building for QT (while, all the other JS frameworks usually do alot of polyfilling)

Available Types:

    JSONInputField - Accepts JSON input, once one presses Save, it will be propegated.
    Button- A Button that listens for a custom event as defined by callback
    Boolean - Creates a checkbox that the user can either check or uncheck
    SliderFloat - Creates a slider (with input) that has Float values from min to max.
        Default is min 0, max 1
    SliderInteger - Creates a slider (with input) that has a Integer value from min to max.
        Default is min 1, max 10000
    SliderRadian - Creates a slider (with input)  that has Float values in degrees,
        that are converted to radians. default is min 0, max Math.PI.
    Texture - Creates a Image with an url input field that points to texture.
        If image cannot form, show "cannot find image"
    VecQuaternion - Creates a 3D Vector field that converts to quaternions.
        Checkbox exists to show quaternions instead.
    Color - Create field color button, that when pressed, opens the color picker.
    Vector - Create a 3D Vector field that has one to one correspondence.

The  script will use this structure to build a UI that is connected The
id fields within High Fidelity

This should make editing, and everything related much more simpler to maintain,
and If there is any changes to either the Entities or properties of
