Django-linkcheck

* Dropped support for Django 1.6 and Django 1.7, the minimal Python version is
now Python 2.7. Django 1.10 is also supported.
* Listeners registration and post_delete signal are now happening in the app
config ready() method. This means that the process can be customized by
having custom AppConfig classes and referring to those classes in the
INSTALLED_APPS setting.
* A new DISABLE_LISTENERS setting has been added to ease deactivation of
listeners registration.
* A task queue is now used to process link checking, so as to prevent exhaustion
of available threads during massive updates.

* Django 1.9 compatibility added.
* When checking internal links, redirects are not followed any longer.
* Added support for the django-admin-tools dashboard, if present.
* Fixed a bug where internal links were skipped based on the external interval
setting.
* Handle situations where content_type.model_class() returns None.
* Allow extra field types to be added via settings. (Used for coverage view only).
* Improve coverage suggested configs - include 'ignore_empty' settings plus a
raw code view via /linkcheck/coverage?config=1.
* Fix - correctly handle tags that are inside tags.
* Fix - don't run pre_save if it's a new instance.

* Added migration folders (missing in the 1.1 package). Also added support for
South migrations (compatibility).
* When a link produces a 301 Moved Permanently redirection, the redirect target
is stored in Url.redirect_to and displayed in the link report.
* Better support for URLs containing non-ASCII characters.

* Minimal software requirements are now Python 2.6 / Django 1.6 (and South 1.0 if
you still use Django 1.6).
* Python 3 is supported.
* Django 1.7 / 1.8 compatibility added.
* notifications.py is now based on django-admin-blocks.
* Linklist classes now support an ignore_empty list to ignore empty URLField values.

Changes:

Bug fixes since 0.6 Please see commit log here: https://github.com/andybak/django-linkcheck/commits/master

Changes:

* Support ignoring (and unignoring) external broken links via buttons in the linkcheck report
* 'Recheck' button in the linkcheck report
* External links with anchors were being reported as broken because we switched to a HEAD request
* One particular url caused a crash in urllib2 when doing a HEAD request. Implemented a workaround: catch the exception and run a normal GET
* Inconsistant use of seconds in some places and minutes in others. Switch to minutes for all parameters.
* Clean up CSS
* Use normal links for navigating between report types instead of javascript+radio buttons
* Removed some unused javascript
* Fixed some issues with anchor links
* Broken link notification count was counting urls rather than links
* Mark length of url field configurable for those not cursed with MySQl
* Remove the pointless disinguishing images/documents/other in Url.type
* Document settings properly
* Remove unused pagination tag from template and thus dependency on django-pagination
* All tests now pass ( because I commented out the one that didn't :-P )
