Size range stamp tool (maybe hue too) - similar to the range options of the new brush tool

With the brush tool now being able to select the range for different options (for example size) I think this could be a nice addition to add to stamps aswell.

Select a range for the stamp size which allows for controlled ranomization of the stamps getting placed. Usefull for things like trees where variance helps getting an organic feeling.

Could also work for hue if slight color variations are desired.
