  Fix reload of timer routes

Use a separate, dynamic list of timer tasks that can be update by other proc than the timer itself (which has no info on the script).
The proc doing the reload, upon success, re-generates the list of timer tasks corresponding to the new set of timer routes.
NOTE: a more complex logic is needed when purging the old set of timer tasks, as they may still be under execution - we use here a pending list where we wait their completion.
