Make '--check-rule' be default for drush cron-run

I've been thinking about this. The way it works now, is that it mimics the actions in the interface, e.g. "run all" will run the scheduled jobs, "run" on a single job will run the job regardless of its schedule.

The use-case for Drush is similar I believe. When you perform a "drush cron-run all", it's because you want to run the scheduled jobs. When you run "drush cron-run ", it's because you want to run that job now.

There's a slight problem though. When using the --cli option, you need the --check-rule to actually make Ultimate Cron double check the "catch up" in the sub-requests.

I think I'll address this in 2.x somehow instead, if it turns out to be a problem there.

The --cli option has been removed, as this is now the launchers responsibility.

The --check-rule has been renamed to --check-schedule as per the new terminology in Ultimate Cron. The boolean logic, however, remains the same. Defaults to schedule checking for all jobs and no schedule checking for a single job.

Please reopen ticket if you disagree.
