Suggestion: Make debounce length a configurable variable

[Captnwalker1]

0.25 is much to quick for most people typing, so that the validation message shows up while they are typing.
At a minimum would double to 0.5, but would be handy to have as a configurable variable.

Hi @Captnwalker1
Thank you for your suggestion!

I've set for reason of most quick validation starting. 0.5 sec adds significant and a bit confused delay for first and last validation checking. Probably this setting worth to leave as default value and pass as argument if it needed.

Let me do this for one week, ok? Or feel free to send PR, I appreciate any valuable contribution!
