Feat: Adds flood.max.unscoped setting

Browse Source 
Before this commit, there was no way to set a different max hop count
for unscoped messages.

Now with this change, by defaul it tracks the flood.max setting, until
a user provides a flood.max.unscoped value, which tax precidence for
packets if ROUTE_TYPE_FLOOD is true.
