Fix label changes table
Fix label changes table

Fix the label changes table so it's more consistent.
In particular: dates with leading "0" become leading space,
renames are given in reverse order, and $e renames are not noted.
See the discussion here:

These changes are based on the modified script scripts/mass-rename
in https://github.com/metamath/set.mm/pull/1468
