Updated language of the readme file to ensure clarification of where scripts should be added to a html page. Also added blank.gif files to the image and editable_images folders to make sure those folders are included with the .rwtheme file. Both folders are referenced in the Theme.plist file and caused errors when previewing in RapidWeaver since Git apparently did not include them as part of the .rwtheme file (seeing as how they were empty folders, I assume).
