- .idx file were re-created if path changed: fix to use relative paths for mods below program folder to avoid issues with UFDs
- Fixed incorrect unicode display in the 'Module Sets' dialog (title and tabs).
- added drag-n-drop autoscrolling in topics tree
- changed behavior of verse detection: now, by default, only the english and 'current language' are used for detecting vrefs.
  The 'vref.languages' config entry ([general] section) can change this behavior as following: Possible values:
  *: means 'All languages'
  [list of languages]: only these will be used (e.g. english,german). 'current' can be used to denote current language

  Examples:
  vref.languages=*
  vref.languages=english,current
  vref.languages=spanish,german
  vref.languages=english
