added tooltip method SetOffsetX(offsetx) added tooltip method SetOffsetY(offsety) added basic clipboard support for the textinput object (0.9.0 only) fixed text object width issues fixed an error caused by pressing a function key while a textinput object was focused fixed the tooltip object not setting the state of its text object cleaned up the tooltip object modified textinput:RunKey to account for changes in the 0.9.0 api
