First try to unify ATTN handling.

this makes it easier to add some more stats later and it removes some
messages.

 RGB Value for activated light:
- aqhome-tool setValue -N nodes/XXXXXXXX/MALRGBWVALUE -v GRWB
+ aqhome-tool setdata -N nodes/XXXXXXXX/MALRGBWVALUE -v GRWB
 
 Example:
   Set color of LED strip to blue (half intensity)
-  aqhome-tool setValue -N nodes/12345678/MALRGBWVALUE -v 0x80
+  aqhome-tool setdata -N nodes/12345678/MALRGBWVALUE -v 0x80

 On-Time after activation:
- aqhome-tool setValue -N nodes/XXXXXXXX/MALONTIME TIME_IN_1/10_SECS
+ aqhome-tool setdata -N nodes/XXXXXXXX/MALONTIME TIME_IN_1/10_SECS
 
 Example:
  Keep light on after activation for 20 seconds

  VVNN is a 16-bit value, lower 8 bit contain the source node address, higher 8 bit contain the
  value id to react to.
  
 Example:
  React to value report messages with value id 7 from node with address 2
