sync with existing resources

As a developer, when I export typealized interfaces, I want to sync keys and values with existing files (instead of overwriting them), to not loose any customizations done in them.

The most significant "problem" currently is, that I do not have a synch-mechanism in place. Currently, The CLI just generates the resource, fast forwarding, overwriting stuff that maybe already has been translated. As code-first is still in a kind of POC phase, atm, so that´s OK for now. But this is definetley a pain point to avoid in the future at all costs.

Diffing those representations is probably not that hard. But the code-first-approach also implies that devs may just rename a property or method, which then would result in a changed key, with little to no chance of accurately being able to diff those with existing resources.
