InitRegion is long, lots of side effects

[jayunit100]

Bug description

The InitRegion function has alot of side effects and is like 500 lines long.
lets split the code up and try to get rid of global func variables so its easy to debug/add logs for stages and so on, as its one of the most common things that breaks in TKG installation.
