devdraw, libdraw: handle keyboard runes > U+FFFF
Runes in Plan 9 were limited to the 16-bit BMP when I drew up the RPC protocol between graphical programs and devdraw a long time ago. Now that they can be 32-bit, use a 32-bit wire encoding too. A new message number to avoid problems with other clients (like 9fans.net/go). Add keyboard shortcut alt : , for U+1F602, face with tears of joy, to test that it all works.
