Misc Fixes ========== -NOTIFICATION_WM_QUIT fixed on android (seems tha way this is reported changed in newer sdk) -WIP implementation of APK Expansion APIs for publishing games larger than 50mb in Play Store -Feaures in the new tutorials are all present in the sourcecode -This (hopefully) should get rid of the animation list order getting corrupted -Improved 3D Scene Importer (Skeletons, Animations and other stuff were not being merged). Anything missing? -In code editor, the automatic syntax checker will only use file_exists() to check preload() else it might freeze the editor too much while typing if the preload is a big resource -Fixed bugs in PolygonPathFinder, stil pending to do a node and a demo
