* Versioned Secrets
√ destroy operation
√ "move" operation
√ numbers and arrays get cast as strings and objects!!
√ show icon or error when secret data is null
√ default new secret path seems to be broken now with multiple folder-structures
√ clear TOKEN as username
√ swap raw and hide values for icons
√ make Hide Values persistent
√ improve error output for move requests

* - Add support for wildcard policies on v2 secret backends
- Update to Electron 4.0
