v0.5 is released! More commands, flags and hotkeys

In this release, more commands, flags and hotkeys have been added! The goal of what-cmd is to ensure that you don't have to google what that command you need to use is or what flags it has (or have cheat sheets lying around everywhere). Now, hotkeys have also been expanded, so if you need a hotkey for linux, the terminal, your terminal emulator, vscode or something else, that will also be right at your fingertips using the -hotkeys option. If there's something you feel is missing, please open an issue and I'll have a look at it and maybe add your suggestion.
