(Mod Request) Fine tune amount of storry teller events

[Sion]

I would like a mod similar to a combination of these mods:

• [MOD] (Alpha 8 ) EdB Prepare Carefully (v1.6.4 - Updated 23 Jan 2015)
• [MOD] (Alpha 8 ) Less Incident Trolling (V 1.1.2 / 27.12.2014)

With this mod you can define how common each event should be, I'm imagining that it would look something like this:
* Mysterious blight:   0 |-------------[57]-------| 100
* Raider attack:           |-----[13]---------------|
* Mechanoid attack:     |[0.3]-------------------|
and so on.
