HOTable -> Kotlin

[wsbrenk]

I'm currently editing the SpecialEvent table and I'm wondering how many classes the functions are distributed in. I would like to have a HOTable class in which everything around the tables is concentrated as much as possible. Maybe we can work on this as part of the Kotlin conversion?!
I really like the approach implemented in HOTableModel. Perhaps the backing up and restoration of the layout can be added. And a switch that lets you alternate the line background color.
