Add 1.2.x branch to authselect weblate

[Pavel Březina]

Hi,
I would like to create a translation component that will track 1.2.x 
branch of authselect. I find Weblate still quite confusing so I need to 
ask: How can I do that?

I remember setting some options on existing components. Is it possible 
to copy all the components and just change the branch name so I don't 
have to set the options again?

Thanks,
Pavel
