To facilitate the concept of live-update, a new command
'reapply' has been added to reapply a given module
to all instances that it had previously been applied to.
Originally, a module designated live-update would automatically
be re-applied whenever it was updated. Adding a specific
command however, allows operators/users more control over
how the new payload would be distributed. Old 'modules'
could be left if desired, or updated with the new command.
