Instant Japan - Immediately Unite Japan as any Daimyo.

I often like to play united Japan from the start. But I'm now too lazy to use console to annex all other Daimyos one by one
So I finally decide to be Bill Gates's model employee and just make a 1 push button to do all the work instead.

Add a decision name "Instant Japan" to immediately gain and cored all the Japan province. Ryukyu island and Ainu's Hokkaido land included.

The decision directly target all the provinces in Japan region. So it should work with any mod and game version.
The decision disappear after 1445.
This doesn't inherit existing troops and ships of the daimyos for maximum laziness.
I'm too lazy to add the localisation.
