Export using chained queries

[jesperkristensen]

Querying some objects require a where-clause filtering on certain fields. We should offer a workaround for that.

For example, to get the Description of all fields in an org, you must first perform a query to get the list of objects, then perform a query for each object to get the list of fields, and then perform a query for each field to get the description.

It should be possible to let the tool perform this sequence of queries.
