Subject: [PATCH] I18n: disambiguate Mix node A and B inputs

In some languages, the A and B sockets need to be disambiguated
because because they can have different letters depending on context.

In Spanish, A is used for B (Blue -> Azul), while the greek letter
alpha is used for A, to disambiguate Azul / alpha.
