Copy the statistics table and graph to the clipboard

Copy All takes whichever tab is open, as N1MM's does: the table off the table tab, a picture of the graph off the graph tab. Copy Table as Text and Copy Graph as Image do either one from either tab. `StatisticsTable` lays the pivot out as the window prints it — the headings, the rows, the Total line — and pads it into columns for the text form, so the grid, the clipboard and Print to File all say the same thing. X11 asks for a picture when the other program pastes rather than when it is copied, so the bitmap given to the clipboard is held until the clipboard is given a different one. Disposing it at the end of the copy killed the program on the next paste; the table pasted into a second Avalonia program reads back lined up, and the picture reads back as a 916x438 bitmap.
