Breaking Changes / Bug Fixes

• Tasks scheduled to run at the same time will be run in registration order.
  This is primarily a bug fix to ensure that "conflicting" tasks are run in a well-defined, deterministic order.
  The breaking change is that unlike the previous version we will not run one-time tasks always before recurring tasks.
  If there is a scheduling "conflict", then the tasks -- whether one-time or recurring -- will always be run in the
  order of registration with the scheduler. (#1) (thanks DylanArnold)
