Adds the ability for windows to persist across all workspaces. Chrome

makes the default that all windows persist across all workspaces and
explicitly disables this for browsers. As part of this I promoted
duplicated code from WorkspaceLayoutManager and
AlwaysOnTopLayoutManager to BaseLayoutManager.

TEST=see bugs, covered by unit tests too.
