RichTextBox picture import, resize, reorient, crop and export

Ver 4 Update on ClsPictureLoader. NEW Crop images before pasteing to RichTExtBox. OLD (But improved)Load picture to RichTextBox with resizing (width, height or proportional). Flip image Left-Right and Top-Bottom. Re-size inserted pictures proportionally with the class (better than doing it by the built-in RichTextBox behaviour). Export RTF document images to BMP. Improved interface with toolbars. Apologies to VER3 downloaders, I forgot that SavePicture is only BMP.
