Some sort of drag-save implementation.

Limitations:
  NetSurf must be running on the Workbench screen
  Only drags to Workbench disk/drawer windows or icons are supported
  Text selection drags are always called netsurf_text_file

Until workbench.library gets a proper function to handle dragging from applications,
this is as good as it will get.

Bugs:
  Pointer imagery needs to change to reflect the dragging, and prevent the usual
pointer changes while the drag is in progress
  Functionality needs to be disabled if NetSurf isn't running on the Workbench screen
(will currently act as if things are being dropped on the WB screen)
  Overwrites existing files without prompting
