module_rescan
Rescans all modules, to find all templates, lib files, dispatch rules, etc. again.
The optional repeatable action argument runs after the rescan has been
requested. The action flushes the file indexer, emits the module_ready
notification, and shows a progress message. It does not wait for all dependent
module work to finish.
