(feature): Add locale settings

[Ledzz]

I would love to change the locale of moment.js. Maybe it can be done with MomentModule.withConfig({ ... })? I've managed to set locale by importing native moment module, but this means I need to import one excess module (which is already imported).

I believe specifying the locale directly on the moment object should do the trick, see #107 for discussion

This does work - however if you then change the locale after the pipe has been rendered, it won't update.

I'm thinking about creating a pull request to implement the non-pure (pure:false) version of the pipes so that they change based on the moment locale changes.
