Distinct event trigger for Cron pipelines

[chromko]

I can't skip some pipelines/steps during cron scheduling.
When I use cron jobs, I can set pipeline trigger with cronjob name to include this pipline during cron execution.

trigger:
  cron: ['cron']

But I can't exclude some pipelines/steps from all cronjobs.
I tried to use something like

trigger:
  cron: 
    exclude: '*'

to exclude cronjobs from common pipelines for pushing code to repo.
But when i commit to repo, I'm getting trigger: skipping pipeline, does not match cron job.

It would be nice to add event type 'cron' to avoid this problem.
I think it'll look like

trigger:
  event: 
    exclude: 'cron'

Thanks

I noticed that DRONE_COMMIT_BEFORE and DRONE_SOURCE_BRANCH are empty when build is triggered by cron. Could this be used to reliably distinguish between regular builds and cron-triggered ones ? Or this is something that will be changed in future versions ?

added support for event: cron in master.
