Improve spanish translation for "Select Top 1 000"

[pmcarballo]

The first text that is shown when a user right-clicks on a table name is "Seleccionar 1 000 mejores" (in Spanish it means "Select best 1 000"). In Spanish it should say "Seleccionar los primeros 1 000" since in this context "TOP" means "FIRST".

@smartguest - Can you work with the loc team to get this looked at? (and make sure it's not an issue in our other products either)
