Title: Creating an "exists" function to check for existence of translation keys...

Refactored the _translate method, creating a _find method that can also be called to check for existence fo the key.

__Motivation:__
This is useful when you are using keys on the client that are based on some string property in an object and you want it to fall back on a default key in case no translation exists.
