Subject: [PATCH] REMOVE: Remove action handler for widgets. (Trac #7174)

The widget functionality has been moved into a module, and this URL handler was the last of the code still in the core app related to widgets.  As well as this commit, there is a related change to the silverstripe-widgets module to add this feature there: https://github.com/silverstripe/silverstripe-widgets/commit/025ee424c4aa27f23513bad36cdaf136b3b9cb64
