New approach: implementation of extended feature in drop nickname event
-----------------------------------------------------------------------
How to:
- in vscp_projdefs.h define DROP_NICKNAME_EXTENDED_FEATURES
- implement somewhere in your project "vscp_hardreset()" and "vscp_wait_ms()"
  examples hereof can be found in /avr/digiprobe_gcc project (vscp_mandatory.c)

If DROP_NICKNAME_EXTENDED_FEATURES is not defined, everything is unchanged,
any old project should compile and work without any touch
