Prepare 0.3.0 release

In this third bigger release we **added support**:
- For exporting articles in the Facebook Instant Article format
- For exporting articles in a plain text format
- To all exporters for `caption` elements that are an empty array
- For `[no-caption]` text in _Google Documents_ below elements (like images or embed URLs), this now returns empty caption for element

**Improvements** were done regarding additional element placement:
- Rework algorithm to place additional elements to better support placing a single element
- Improve behavior of multiple calls to `Article#place_additional_elements`

One potentially **breaking change** was added:
- Remove deprecated `#register_html_element_exporter`, use `#register_element_exporters` instead

**Fixes**:
- Fix AMP export of Twitter tweets
