This commit makes 2 changes to the generic Logitech 27 MHz keyboard keymap:
1. It moves some codes from being keyboard specific to the generic 27MHz
mapping table, these codes do not conflict on different models and at
least the c1019 - c101b codes are not only used on the MX3000 keyboard,
but also on the S510 Remote control
2. Add a bunch of new codes found on the S510 keyboard and S510 remote control
