Version 1.0
Finally at version 1.0 after nearly three years of work on this mod, off and on, with a long hiatus. 
This release includes a lot of minor improvements again, listed in the changelog below, and is save-game compatible with 0.9* versions.
I've added a minor country event starting in the 4th century to include some historical flavor for the foederati of the late Roman Empire. A Latin culture great power (usually Rome, but could be the Etruscans) that borders a province with a migratory germanic tribe will get the event to vassalize that tribe, or create a new tribe from a part of it, if it owns many territories, in exchange for giving all the territories in the same state area.
A random successor chief appears in the event window, and if a new tribe is created then he becomes the new ruler.
There is, however, a -50 modifier added to the loyalty of the new tribe, alluding to the questionable loyalty of the historical foederati, which eventually led to the final dissolution of the Western Roman Empire as a polity when Odoacer deposed Romulus Augustulus in 1229 AUC / 476 CE.

Will Duomogan of the Dwaldes clan revolt against Rome? Probably not.
This is compatible with Invictus 1.3.1b "Ashoka" but it will need further updating for any map changes in a future Invictus release.

-some countries that did not get the Antonine Plague (because they were too small [<100 cities], or created after the triggering dates) would get both plagues during Cyprian pandemic, because the global variable to trigger the two plague events was the same one!
