Add edited timestamp to annotation headers

Update the `time` utility module to more closely match
our current conventions. Also make time math consistent
(always use `ms` units), organize for concision and
rename a few references for clarity.

The only functional change is the addition of the string
"ago" to some of the relative time templating.

Refactor annotation events

Remove state logic from root-thread and place it in corresponding stores:

- deleteNewAndEmptyAnnotations moves to drafts and renamed to deleteNewAndEmptyDrafts
- events.BEFORE_ANNOTATION_CREATED's logic moves to createAnnotation in annotations store
- selection store handles REMOVE_ANNOTIONS action directly
