[aur-dev] Fix for some plural strings

[Safa Alfulaij]

Hello Lukas,

About the constants no problem leave them as they are, but the rest not.
Not all of the languages has one form only after 1, Arabic (for example)
has 6 forms, 4 of them is after 1. This is not a good reason for not
accepting my patch for these at least :)

Note: I mix always between "has" and "have", so I am sorry for my poor
language :\
Regards,
Safa
