[Feature Request] QInnerLoading delay

[Techn1c4l]

QInnerLoading is a great way to show that app is busy. However, sometimes an operation is performed quickly, causing loading spinner and overlay to flash in and out which doesn't look good, especially when you show multiple loadings in a row.

There is however a very simple solution - adding delay to the loading indicator for about 200-300 ms. If an operation finishes quick enough, there is no need to show the loading indicator. If it takes long enough, the indicator will be shown.

Currently, we have to use custom solution with setTimeout to change the showing prop only after set delay. It would be much nicer if the component would have a delay prop which would allow the described behavior.
