1. Added German localisation: thank you to Christoph Schmitz.
   
2. Logbook table now supports data sort by columns and retains the column order between launches.
   
3. Fixed localisation replacement string issue with Event Name/Notes field template.
   
4. Fixed import data issue: events older than the previously last imported event would not be imported even if "All Events' was selected.

Note: To migrate from the default English language to a localised version, to ensure that the assigned Period names are re-generated into the localised language, you must:

1. export all exisiting events using the Export facility
   
2. delete all events
   
3. import the export data file

This is a recommended update to all users.
