This commit introduces a new component: the layout component.
Its purpose is to make abstraction of most generic components and
classes when writing a view template or an action.
To make use of this component, we also needed a new system to pass slot
from the parent of the layout to the control panel. This was done in a
hacky way and is meant to be replaced as soon as Owl provides a built-in
way to pass slots.
The control panel has also been slightly tweaked to default its props
from an environment's newly introduced key: the 'config'. This has been
done to reduce the amount of props passed to the layout and search
subcomponents.
