getDirectorym, getImage, setBatchMode

Feedback from Christoph Spahn:

Really awesome cheat sheet, Robert! What I additionally use very often: getDirectory() to select input/output folders, setBatchMode(xy), getImageID() to render image selection title-independent. Also, duplicating images is very handy in macros. Might be too specific, though :)
