[cp900] Treat CP900 like the other CP-series printers.

Browse source 
Turns out its extra 4 bytes of footer can be safely ignored and not sent
 to the printer.  So don't bother, and simplify the code a little.

 Also, this adds support for SELPHY_PID/SELPHY_TYPE environment variables
 that allow for unknown PIDs to be used without a recompile.  Useful for
 testing purposes!
