[amfine-soft-scheminel]

Hi

Goal : Introduce the hability to limit QPopover height on QSelect like it's already done on QAutocomplete.

This PR goal is to be able to implement with QSelect the workaround describe in :
#2530
In case there is too much options to display it'll help to limit QPopover height.

Thx

Thanks for supplying a PR. Changed prop name to "popup-max-height" though.

Nota Bene : I suggest max-height as it was max-height in AutoComplete.

Maybe you should use the same properties in both Widget ?

Thanks for accepting my PR.

I think it's better for the props name to be as explicit as possible, otherwise in this case some devs might think max-height is referring to the input max-height.
