Loading Levels Not Validated

[PythooonUser]

Summary

Any file can be loaded. Even ones that do not exist. They default to a new project layout. I would expect an error message in that case.

Work

• Add ability to show error messages
• Allow only valid level extensions to be loaded
• Check if level could be loaded successfully

For this question to be answered we need to know more about the loading process itself. For .bin and .dat formats, especially .bin, are there any magic characters, specific bytes, data structures etc. that need to be valid? Or is it just waiting for errors to be thrown when trying to parse the level files?

For the legacy .png format, are there any validations we can use? Like colors, size etc.?
