Remove RendererBackend from visual settings.

It recommended to use the OpenGL renderer. Only in some special cases
it could be better to use the SDL renderer. E.g. for some SiS GPUs.
This needs to be done now manually in the settings file.
Add armory which produces daggers.
Add placeholder gfx for dagger.
Move format call for translation lookup to really

format the string.
