Document and extend BoringWindows to support multiple sources of boring.
Ignore-this: 7375c8912ede6a6a44db4a4b91ffbc33
The Replace and Merge messages are added to support layouts sending a list of
windows that should be skipped over. The sources are tagged by a string key, so
it is possible though unlikely for different sources of boring windows to
interfere with eachother.
