Several UI improvements and fixes in the HTML export
Key highlights:
- Several fixes of the table and deep traceability screens. Due to the similarities, the Traceability and Deep Traceability screens will likely be merged in the near future.
- The Requirements-to-Files traceability UI is receiving further tweaks and improvements. It is approaching a releasable state. The feature is being tested against StrictDoc's own documentation
- Several fixes of the edge cases related to the file search (finding .sdoc files and _assets folders).
