Transifex plurals

Hi

I saw some mistakes for plurals in the last translations in Transifex on
the SimpleWelcome project. (I fixed the es translation)

For a plural form in Transifex you have something like that on the left:

one: 1 item
other: %1 items

On the right you have two fields. In this example the French translation
would be :

1 =C3=A9l=C3=A9ment (in the first field)
%1 =C3=A9l=C3=A9ments (in the second field)

Basically in Transifex, every text that has color is not a text to
translate but an indicator

Transifex also show spaces in blue, and carriage returns you'll have to
type in your translation
