Permissions for safety overrides should be more fine-grained

[Commoble]

Current situation: One config value for minimum permission level to be able to ignore the blacklist and to overwrite blocks

Possible improvements:

• Split blacklist override and overwritability into separate permissions
• Make configs to only allow overwriting in creative mode
• Add a keybind that users must be holding to enable block overwriting

Added a keybind for using the bag at creative level in 1.2.0.0
