 * rename-object-by-type.js
 *
 * This extension adds a 'Rename Object by Type' (Ctrl+Shift+R) action to the Map
 * menu, which can be used to bulk rename custom objects which have a Type, very 
 * usefull if exporting the map to Godot.
 * I have based this script on https://github.com/mapeditor/tiled-extensions/blob/master/find-object-by-id.js
