Add optional `fields` to change feed selectors

When using selectors with `include_docs=true` can specify an optional fields
array in the POST request JSON body.

Each element in the array can be a json field (or even a key path
specified as field1.field2...). Resulting documents will contain only the
specified document fields.

For example:
```
http://.../d1/_changes?filter=_selector&include_docs=true

{
    "selector": {"z" : {"$gte" : 1} }, "fields": ["field1", "field2"]
}
```
Will first select only document with "z" value >= 1, then will return only field1 and field2 in documents.

```{ "field1": "field1value", "field2": "field2value"}```
