#1153 Export Records and Relations

[Shaun]

The ability to choose to export a set of records and all related records based on the relations defined in phpMyAdmin.

Use Case:
I would like to move a customer from 1 database to another database. I need to export their account record, and also any campaigns referencing that account and also any groups referencing that campaign and so on. Ideally it would be a top down export that let's me choose the account record and then looks for all references to that account record and does so recursively down the tree. It would use the relations I have already defined in phpMyAdmin.
