2.0.0: Anonymised data exports

This new major release for magedbm2 includes the following:

• Removed dependency on n98-magerun
• Support the generation of an anonymised data export with the export and import commands (great for reproducing those bugs that need the data in your database, without jeopardising your sensitive customer data)
• Add project-level configuration so you can ship a .magedbm2.yml file with your project and add project-specific configuration in there
