v0.4.0

What's Changed

• feat: add multi-window support (finally) by @cst8t in #22
  This means you can finally have as many instances of Gitmun open for as many projects as you want (as long as your computer can handle it)

• feat: add i18next localisation by @cst8t in #23
  This should set things up nicely for when a Weblate instance is setup for crowd sourced translations.
