Move fields from one entity to another

@joachim: Would you agree with my point in #8?

Still makes sense to either disallow to copy a field from one entity type to another OR (even better) copy it over correctly.

It's quite dangerous, if someone clones a field across entity types currently, isn't it?
I suggest only showing current entities fields, until this is properly implemented

If you agree, I'll provide a patch for that until someone has the time to fully implement support for that.

Update: I created a separate issue for that now: 🐛 Cloning to other entity type bundles should not be allowed, until it's supported Active would appreciate a short feedback @joachim before I start with the implementation.

It should be fine, but you have to:

a. check the field name isn't already used on the destination entity type
b. clone the field storage as well as the instances

Thanks @joachim!! :) So this issue can still be used to implement the full support!

Ok.

I'm going to put this issue to wontfix, since you're working on the new one, and this issue's summary is about field data, which Field Tools isn't going to support.
