scripted-diff: replace PoissonNextSend with GetExponentialRand
This distribution is used for more than just the next inv send, so make the name more generic. Also rename to "exponential" to avoid the confusion that this is a poisson distribution. -BEGIN VERIFY SCRIPT- ren() { sed -i "s/\<$1\>/$2/g" $(git grep -l "$1" ./src) ; } ren PoissonNextSend GetExponentialRand ren "a poisson timer" "an exponential timer" -END VERIFY SCRIPT-
