v3.9.3

• Fix weird behaviour of Hide window to tray with the close button option (#306).
• Refactor localization files loader class (L10N).
  • This make WebCord also load localizations from associated locales, giving higher chance to display still relevant localizations rather than fall back to English.
• Refactor Content Security Policy class.
  • This changes a bit the purpose of this class – it should be only used when modifications are going to be made on the Content Security Policy, rather than replace the actual string which includes it.
  • This also makes the class value read-write, so it can be set and converted automatically to the proper format.
• Add 🇷🇺️ Russian localization files by @dsrev (#308)
• Try to sign macOS binaries with the default configuration.
