The Glossary implementation used to be more suffisticated in swt. Some
features could not yet be reimplemented, since the fx integration does
not yet support it.
- Highlight Glossary terms when they are used in text fields as requirements, comments etc.
- Add possibilitiy to right-click on words in text fields as requirements, comments, etc to add them to the glossary.
- Autocompletion for glossary entries in text fields
