Issue:
Bad field name when selecting a field using backquotes
```sql
genji> select `a` from foo;
{
  "`a`": 1
}
```

It should be:

```sql
genji> select `a` from foo;
{
  "a": null
}
genji> select `some "long" string` from foo;
{
  "some \"long\" string": null
}
```

Pull request description:
Display unquoted field names in result fields
This PR fixes #64 by adding a special case in the parser for FieldSelectors. It makes sure we are always displaying the unquoted version of these fields instead of the raw version entered by the user.
