Add new string members to GimpImageMapTool and use them instead of the resp. fields of GimpToolInfo. Change ::get_operation() to return the operation name and a lot of strings for the UI, and create both the GeglNode and the config object in GimpOperationTool. Lots of various cleanups in GimpImageMapTool subclasses. This is an intermediate state on the way of making the whole filter applying mechanism more generic and less depending on subclasses.
