Native Export action / VBO for entities

Problem/Motivation

In the past https://www.drupal.org/project/export_action_for_default_content seems to have provided what this issue asks for, but the module has no pushished release currently and it's unclear, if it's compatible with 2.x

So I'd vote to integrate the functionality directly into this module, instead of using a separate module in the future.

Might go into a submodule so it can be easily enabled if needed.

Steps to reproduce

Proposed resolution

Remaining tasks

User interface changes
