Introduce Info / VBox / HBox / Labeled for more consistent layouting

Summary:
This diff introduces a set of components:

VBox: use this to group things vertically, it little more than a container that fills the full width and adds bottom margin (see screenshot: creating distance between the boxes)

HBox: use to divide a space horizontal in two, and distribute it over two children, supports growing the right side, left side or both equally. In the image used to reserve the necessary width for the image, and give the remaining space to the text

Info: A component that shows a message, prestyled with one of the four types: info, error, warning, pending.
