Remarks

We need to do this so that we don't have to maintain a huge static list of all field names and their definitions otherwise we'd have to dynamically add/remove definitions anytime languages are added/removed, etc... For example, we have things like nodeName and __Published which are also used for culture fields like nodeName_en-us and we don't want to have a full static list of all of these definitions when we can just define the one definition and then dynamically apply that to culture specific fields. There is a caveat to this however, when a field definition is found for a non-culture field we will create and store a new field definition for that culture so that the next time it needs to be looked up and used we are not allocating more objects. This does mean however that if a language is deleted, the field definitions for that language will still exist in memory. This isn't going to cause any problems and the mem will be cleared on next site restart but it's worth pointing out.
