This is a very simple modification that affects a very large number of files in Contiki: Cooja,
/platform/cooja, Collect-view, Coffe-manager, and Cooja simulation files (.csc).
I've gone through Contiki to update all references I could find. Nevertheless, this commit will likely
break external dependencies, like saved Cooja simulation files.
Documented intent is to update with probability 1/NEW_TOKEN_PROB where
NEW_TOKEN_PROB is 0x80. The current implementation updates with probability
1/2. Update NEW_TOKEN_PROB and the expression to keep existing behavior
while correcting the calculation.
