Add keywords to the class reference

Allows for finding methods, properties, signals, constants,
theme items and annotations more easily.

- Allow "keywords" attribute in aforementioned locations
  in the class reference XMLs
- Extends doctool, to preserve these attributes
- Update the XSD schema for the class reference
- Update the RST generator to include a meta tag for class keywords
- Update the editor help to support filtering by keywords
