Version 8.0.0 ready

[afpineda]

Version 8.0.0 has been released.

There are subtle improvements. Most custom firmwares from version 7 may work without changes.

• The limit to 64 firmware-defined input numbers has been increased to 128.
  Now, you can use the full 128 range of input numbers anywhere in the firmware.

• Input routing:
  This is a new feature that allows a button press to be routed to the user interface, typically to select another dashboard.
