Theme modifiers can now be defined as theme settings, this allows for
site operators to override behavior of theme modifiers.
New syntax is:
```
{
...
"modifiers": {
"modifier_name": {
"type": "setting",
"value": "setting_name"
}
}
}
```
This also introduces a new theme modifier for serialize_post_user_badges. Name of badge must match the name of the badge in the badges table. The client-side is updated to load this new data from the post-stream serializer.
