Extend Dropzone widget (#5597)

Browse Source 
* Extend dropzone widget with optional actions invoked after tm-import-tiddlers message has been sent. Allows triggering an alternative UX for the import

* Allow restricting a dropzone to specific mimeTypes via mimeTypes and mimeTypesPrefix attributes

* Use a mimeTypesFilter instead of the mimeTypes and mimeTypesPrefix attributes

* Updated refresh handling

* Syntax cleanup

* Replace references to mimeType with content type for consistency with existing documentation. Update documentation for DropZone widget
