Layout editor enhancements
========================
Split existing columns dropping new components
Change the span distribution of a row (using the separator as a slider?), instead of having to delete and create the row again
Fix the preview feature
Add component preview support (i..e a radio button should display a radio button, not the label "radio button")
Support moving rows using drag and drop
Drag a component directly in a row and automatically creates a 12 span column
Column component drag preview on row
Create a tab support for new layouts and a way to define if that layout is a multi tab form or a multi step form
Investigate the possibility to put the plugin editor in a dock in order to maximize layout space
Write an upgrade tool from existing layout to this new (multi tab) version

Pere’s changes (https://github.com/pefernan/uberfire-extensions && https://github.com/droolsjbpm/livespark/tree/graphic-editor):
HasDragAndDropSettings: send other information information across the Drag & Drop event, not only the draggable type
HasOnDropNotification: notify the draggable component that’s been droved
HasOnRemoveNotification: notify the draggable component that’s going to be removed
DynamicLayoutDraggableGroup: allow to add / remove dynamic component groups on the components palette. Also allow to add / remove child elements of the dynamic groups.
BootstrapLayoutGenerator: lookup new DraggableComponent iinstances before render them.

Three new type of panels:
Regular tabs;
Carrousel;
Multi Step Screens (asking if a component is ready or not).
