Add emailing (or RSS) of reports (enhancement)

[matturn]

It would be great if there was the option of a regular email (or RSS feed) containing the broken URLs.

I would like to second this proposal.

It would be great to have an enhancement within tool_crawler with this rough functionality:

• There is an additional scheduled task "Send link crawler reports" which is configured to run once per night
• There is a new message provider "Receive link crawler reports" which is enabled by default for all users
• If the scheduled task runs, it will
  ** Iterate over all users who have enabled the message provider and who have the capability to view the link crawler report in at least one course
  ** For each user, iterate over his courses to see if the link crawler report contains any links to be reported
  ** If there are links to be reported, compose a message which contains basic link crawler figures about all courses and links to the particular link crawler reports in each course.
  ** Send the message through the notification system

In a second stage, the message could also contain a section which highlights the courses where things have changed since the last message, e.g. "In course 'Mathematics 101', there is 1 new broken link"

Cheers,
Alex
