- Added `.toString()` method to WPRequest objects, which returns the full
  rendered URI for a query
- Added `.before` and `.after` chaining methods to specify date queries
- Improvements to integration tests & documentation

**Deprecated Methods:**

- `._renderURI()` method on WPRequest object (use `.toString`)
- `.post()` HTTP method on WPRequest object (use `.create`)
- `.put()` HTTP method on WPRequest object (use `.update`)

**Props for this patch release:**
