Plurals Localisation

We should try to level up the localisation to a new level by localising plurals. Not sure if there is some library for .net/javascript.

Here I throw some ideas:

Plurals definitions for different languages using lambdas:

This is the package I think we should use:

this looks quite useful too:

What will we use server side?
