- added `textMetadata` KorAPConnection method to retrieve all metadata for a text, based on its sigle
- added `webUiRequestUrl` column also to corpusStats results, so that also virtual corpus definitions can be linked to / tested directly in the KorAP UI
- added on-click action to open KorAP query also to highcharter scatter plots
- unless `metadataOnly` is set, also tokenized snippets are now retrieved in corpus queries (stored in `collectedMatches$tokens`)
- uses server side tokenized matches in collocation analysis, if supported by KorAP server
- fixed regional demo (will be updated again soon)
