Sample canvas renderer

[lifeart]

Todos:

• cleanup codebase
• mark component output as already rendered (using weak map?) - to do proper list "relocation"
• add test for multiple roots inside list item (list relocation tests)
• in general, we should always have unstable component wrapper for lists if we have > 1 root nodes, or this node is not an component
• add test for list where list item is a component with it's own dom, + nested components (outside main component DOM)
• remove $nodes property, and use $_fin to declare RENDERED_NODES_PROPERTY symbol on instance.
• inside renderElement function replace RENDERABLE node to actual node (by index) inside RENDERED_NODES_PROPERTY array
