I think we can avoid the declaration of `risk-player-inline` in files using a "declarated" template. I used it quite a long time ago, I don't if it's still working. It looks like:

```HTML
<polymer-element name="risk-history">
  <template>
      <!-- Declare a reusable template -->
      <template id="risk-player-inline">
        <img src="img/avatars/{{ avatar }}" class="img-rounded" alt="Avatar"> {{ name }}
      </template>

      <!-- ... -->
      <template ref="risk-player-inline" bind="{{ player }}"></template>
```
