Editor: upgrade quest data files automatically
Created by: christopho
When loading a project, if ObsoleteQuestException is catched, ask the user if he wants his quest data files to be automatically upgraded. The automatic upgrade should be done using the Lua scripts in tools/data_files_conversion, showing their output to the user. An automatic backup should be performed first.
This improvement requires to include the Lua conversion scripts to the jar archive of the editor.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
