- Sony: Files with incorrect checksum are no longer rejected. Information about a bad checksum is visible

unter File / File Information. (The TV seems to ignore bad checksums during the import and the official
  Sony PC Editor ignores bad checksums and write incorrect ones, depending on the file format version)
- Updated Hungarian translation. Thanks to efi99 on Github!
- Minor cleanup amongst translation (setting @Invariant for constant strings and unifying "..." in menu items that open a new dialog)
