New optional parameters are available to select the database:
Mixins::DocumentQueries
* get <id>, <db>
* all :database => <db>
* first :database => <db>
Mixins::Views
* view <name>, :database => <db>
* all_design_doc_versions <db>
* cleanup_design_docs! <db>
Mixins::DesignDoc
* refresh_design_doc now only updates the design_doc _id and removes _rev
* call save_design_doc to save and update the design_doc
* call save_design_doc_on <db> to save the design doc on a given
database without modifying the model's design_doc object
Design (core/design.rb)
* new method view_on <db>, ...
Bug fixes:
* design_doc_slug in mixins/design_doc.rb was using an empty document
to calculate the slug each time
* method_missing in core/extended_document.rb now passes a block through
