Adds tracking of external broken links to the SilverStripe CMS without revising content in the database
The external links module is a task and ModelAdmin to track and to report on broken external links. It is maintained
by Kirk Mayo at Silverstripe.
This is a fork which removes a core piece of the module's functionality. With this fork installed, the module will no
longer write the
ss-broken css class to broken URLs. The reason for this change is that saving the modified record
to the database changes the publication date of versioned content, pushing it back to the top of RSS feeds and Recently
config.yml file contains a boolean value that can be used to turn the "add class" functionality on and off.

A new report is added called 'External Broken links report'. When viewing this report, a user may press
the "Create new report" button which will trigger an ajax request to initiate a report run.
In this initial ajax request this module will do one of two things, depending on which modules are included:
In either case, the background task will loop over every page in the system, inspecting all external urls and
checking the status code returned by requesting each one. If a URL returns a response code that is considered
"broken" (defined as < 200 or > 302) then the
ss-broken css class will be assigned to that url, and
a line item will be added to the report. If a previously broken link has been corrected or fixed, then
this class is removed.
In the actual report generated the user can click on any broken link item to either view the link in their browser,
or edit the containing page in the CMS.
While a report is running the current status of this report will be displayed on the report details page, along
with the status. The user may leave this page and return to it later to view the ongoing status of this report.
Any subsequent report may not be generated until a prior report has completed.
