MCE::Core::Input::{ Handle and Sequence } to not impact the OS kernel; the
result is better performance, yet graceful

- Set chunk-level accordingly to list mode
- New upstream release 1.815
- Fixed divide-by-zero error in MCE->yield
- Refactored code for the interval option by moving the code to the manager
process, which allows the manager process to accomodate the next available
worker ready to run; previously, a worker taking a long time resulted in
empty time slots

MCE->sendto to work reliably with App::Cmd and App::Cmd::Tester; see
