Executions (#24150)
* Execution (you monster) not done * woops * more stuff * Melee executions * Prevent executing those who can interact * Better checks for if you can execute * Scale the execution time of a knife with its attack speed * Translations for fucking up an execution * rename some functions * Properly scale execution speed of melee weapons * Fix checks in CanExecuteWithAny * Allow executing yourself (funny) * More versatile localisation * Suicide with guns * Popups for successful gun executions * whoops * Stop flare guns crashing the game on executions * Various tweaks * Remove some old usings * Pacifists can no longer execute * Remove unnecessary check * Use CanShoot in gunsystem * Capitalisation in ftl string * Fix melee executions not playing a sound * localisation tweaks
