add the start of an icon button. the stupid number of svg's needs to be wrapped into two with svg elements for them, geometry isn't managed right (e.g. we ignore text width) etc.. but the basics exist. should be usable by hacking's end tomorrow, and then we can play with using them to pop menus and expanders. i'll get to Phase yet ;)
