QmlDesigner: Generate qml id from image file name

Browse Source 
When dragging an image file to create a Image or Texture item,
base the id on the file name rather than setting it to generic name
based on type.

This includes cleanup of AbstractView::generateNewId to remove
redundant and unused code as well as an option to provide a fallback
id prefix.
