Feature Request: Monitor other things than the File System to trigger builds

[robertoandrade]

ie:

• Monitor health/status of a remote service, ie: ping 8.8.8.8 (trigger some command upon it)
• Monitor a remote git repo status, ie: git show origin/master --oneline | head -1

Would be nice to trigger a build automatically, like Jenkins or some other build systems that allows you to monitor for remote changes somehow, pull them in and then trigger the build.

Perhaps this a feature request for "plugins" instead of these features actually making into snag core :)
