Export everything

[ghost]

Is your feature request related to a problem? Please describe.
So far it is only possible to export as csv, and even there, not everything is covered.

Describe the solution you'd like
It would be great to fully export all intents, entities, slots, etc. so it can be implemented as a corpus or .nlp model in custom chat bots.

After all, it does have the save/export methods

Is there any way to do something similar with the mongodb database? It stores everything, which is good, but how can I take that and train it to my own custom chat bot?
