added PAL60 specification. even though it isn't a real specification it is more convenient and provides better user feedback moved FrameInfo into frameinfo package, now called Current as in frameinfo.Current clarified storage of requested specification by the television: how the television is probed for the specification has changed, in particular the current spec is retreived via the GetFrameInfo() function. in fact, this was how most other packages did it but there also existed a GetSpecID() which was uncessary GetReqSpecID() and GetCreationSpecID() removed, replaced with GetResetSpecID() and IsAutoSpec() simplified SetSpec(). removed the force argument removed reset option for vcs.AttachCartridge()
