Makes that message dialog movable with Shift-Left-Click
You can move it by shift-clicking and dragging
It can also be scaled with the mouse wheel (while pressing shift)
Note that the frame will be made click-through when not holding shift so it doesn't block quest givers or mobs underneath it, but if you want to right-click the frame away you need to hold shift as well.
This does not work with ElvUI, which already supports moving it with /moveui
Slash Commands:
/th 0.8 - - - - sets the scale to 0.80 (can be between 0.50 to 2.00)
/th reset - - resets the position and scale
