Build Height Slider

An in-game option to change the room height without having to edit the DAM.

We have the ability to set the grid to one of three heights at map gen. Now with the most recent update we can move objects on the Z axis. Additionally, we have found that an ambitious map maker can change the room height by editing the .DAM file.

What I would like is the ability to adjust the roomHeight setting in-game, not just to the 3 presets, 0.2, 1.5, and 3.5, but a slider that would move the build grid up and down. The slider could appear on the edit screen, or on the Draw Rooms menu. The slider would show you the height it is set to, from -3.0 to maybe 4.2 (plus the 1.8 walls of a room would reach the max height 6.0.)
