Backwards compatible changes
1) load_level, load_format and FormatWrapper.is_valid can now take any type as input.
2) Moved FormatWrapper.exists has been moved to DiskFormatWrapper
FormatWrapper is an alias for DiskFormatWrapper so this should be backwards compatible.
3) FormatWrapper.create_and_open as been replaced with FormatWrapper.create followed by FormatWrapper.open.
