Major changes to the scheduler, previously only used by the main loop. Revamped Scheduler. Functions can be removed, have multiple schedules, have their scheduling changed, etc. Scheduler has a unittest. Checked all pass. Main loop scheduler moved to mde. Draw-on-demand currently disabled, simplifying this. Made mtunitest.d remove the temporary file it uses afterwards. committer: Diggory Hardy <diggory.hardy@gmail.com>
