[Enhancement] ⏳🔎 User configurable time delay in Search TextBox for Live Search

[AltoRetrato]

Hi, Martin!

Thank you for your hard and wonderful work on Aedict! I've been using it for many years, and always recommend it to any Japanese learner I meet!

There's one suggestion I'd like to make to improve it, though - a time delay in the Search TextBox. While I think "Live Search" is great, it clearly eats the battery away when I'm doing a lot of searches. Being able to disable it is nice (I have it disabled most of the time), but I think an even nicer alternative would be to add a configurable time delay (e.g., in ms) to enable automatic / "Live" search only after that amount of time has passed after the last entry in the TextBox. That would bring the best of both worlds: no need to tap the search icon for every search while still being battery-friendly! :)

Thanks again for your great app!
