Would be nice to have a feature where the gap detector agent creates an event every time its run when a gap is detected instead of just once.

Simple example of use case, if I have a backup job that pings a webhook agent -> gap detector agent and that backup hasn't run in two days. I'd like a constant reminder that the backup is still not running.

Seems simple enough to do:

• Add a default boolean option to the default on line 32.
• Add validation check
• update the check function to look for that option or default to current behavior if its missing.
• Update the description

Looks like the line that is preventing it from happening now is:
https://github.com/huginn/huginn/blob/master/app/models/agents/gap_detector_agent.rb#L59

I will give this a try, though I've never written ruby.
