Now deals correctly with a content view containing just a list, and adds a lot more built-in functionality: ability to show custom text for an empty list, and indeterminant progress while populating the list. In addition, reworks transaction committing to be more aggressive about committing the transactions as the containing activity moves between its states (rather than waiting for the activity's handler to process the transaction message whenever that may finally happen). And fixed a bug with saving/restoring state of transaction replace operations. Change-Id: I9617a0c4f248b50a61b319910323639b6de24f73
