Ref T13120. Ref T12414. See PHI145. See PHI473. This partially modernizes AlmanacService transactions by moving them to ModularTransactions.
This isn't complete because the "update property" and "remove property" transactions aren't modularized. They still work, since the parent Editor implements them, but they no longer render properly on the timeline since the Transaction object no longer has rendering logic for them.
Tentatively, I'm going to try to convert the rest of the Almanac objects and then modularize those transactions. (Currently, all of Binding, Device, Namespace and Service support properties, although they can only actually be edited on Service, Device and Binding.)
If that turns out to be really tricky for some reason I can just copy/paste the timeline rendering for now, but I think it won't be too hard.
