data: showing local symbols

- added local symbols to storage
- added tests for local symbol parsing
- added MessageActivateLocalSymbols to activate local symbols in code view
- TokenLocations now store their LocationType instead of a plain bool "isScope"
- moved LocationType from TokenLocation to separate file, since it is also used in Annotations now.
- added local_symbol in stylesheet to define a style for hovering and activating these elements
- renamed location to token in stylesheet
