ui/data: cleaned up UI and parsing

* HOT FIX: typename not always correctly split to name hierarchy
* show node main if available as first active token after parsing
* show all contents of namespaces if searched for
* added missing enum type and enum value usages
* added inheritance for structs
* removed MessageActivateToken and replaced it with MessageActivateTokens
* activating correct nodes for clicks in GraphView and CodeView
* no graph change when clicking an edge, but highlighting the edge instead
* only show active nodes without connections when multiple are activated
* fixed snippet sorting to put file that contains declarations on top
* set sizeHints on CodeView and SearchView to increase their initial size
