Add support for JSX inside Svelte files?

[bfanger]

Look into adding support for JSX syntax into *.svelte files.

<script>
import { CompoundButton, CompoundIcon } from "office-ui-fabric-react";
</script>

<react:CompoundButton icon={<CompoundIcon />} secondaryContent="Secondary content">
  Example
</react:CompoundButton>

The icon={<CompoundIcon />}
Should be preprocessed into:
icon={createElement(CompoundIcon)}
