Import export updates

Import / Export Fixes

• Export the box order (was in import code, but not in export)
• Export all game levels (including 0)
• Export level buyout as the level number instead of id (otherwise on import references are incorrect)
• Import Game Level description (was in export code, but not in import)

Export New

• Box: Add avatar_path element
  • Support use case where box images may be stored in a path other than /upload/ (for example in a docker image). Allows export/import to utilize these and not lose the references during import.
  • If the box avatar path does not include /upload/, the avatar_path will be added to the export xml, otherwise it isn't added.

Import New

• Add import_options element
  • Options to clear (drop all) levels and corporations during import allowing for overwriting of existing data
  • Element attributes:
    • clear_levels - Set to "1" to delete all levels before import starts
    • clear_corps - Set to "1" to delete all corporations before import starts
    • Ex <import_options clear_levels="1" clear_corps="1" />
• Pass tuple to box.avatar during import for new avatar_path support

Box - avatar setter change

• Check if value provided is a tuple, and if so set avatar_path from second value
  • If avatar_path is upload - handle like previously to create image based on box.uuid
  • Otherwise use avatar_path as-is for image path, the assumption is this will only be from xml imports

View

• Game levels view: For level buyouts, added level name in addition to level number to make it clearer
• Game levels edit: Fix for level buyouts, set selected item in the list properly when opening for edit

Other

• Game level deletion fix

@eljeffeg - This one has a bit more to review than the last, but addresses some things we've run into as we explore the import/export options more. It also has a few fixes for ui/functions outside of the export/import directly as noted.

I can't recall why we excluded level 0. No issues on import?

[bmartin5692]

No issues, and skipping it meant our export didn't have our first level details. The code actually ignores existing levels and boxes during import anyway. It is part of the reason I added the import_options so we could have it start fresh and load it fully.
