Make the components not vissible while loading

[spynetS]

Right now when we have a component

<template rapid-name="comp" >
<h1>{props.children}</h1>
</template>

<comp>TEST</comp>

before rapid has loaded and replaced everything
the <comp>TEST</comp> will be rendered as TEST in the dom

Plan

One could wrap the component initlization inside a template which would make it not render
but this would look ugly

<template rapid-render>
   <comp>TEST</comp>
</template>

Or

<template component-name="comp">
   TEST
</template>
