Feature Request: Dashboard listing all nodes changed since last deploy

[hfloyd]

There is a challenging Editor workflow issue where often changes are made to multiple nodes, and those need to be "remembered" by editors for deployment. Especially changes to related nodes, like Media items (see: #220). It would be great if there were some way to show Editors a list of "changed" nodes (of all types) since they last deployed anything, and the ability to queue those nodes for transfer.
