Updated render
Further separates loom from DOM components.

This commit introduces a new base class fort DOM components (`dom/component/gadget`). The previous functionality of `dom/component/widget` has been split and all loom related code has been retained in the original module while non-loom code has been transferred to `dom/component/gadget`.

This paves the way for non-loom based web components (I'm looking at you react and possibly even angular) to be able to interract cleanly with troop components without adding any extra bloat.
Remove relocated modules.
Move modules from `component` namespace.
