Qt: KeyboardInputInterval - allow more relaxed typing for keyboardSearch

Gtk popped up a search box when typing in the tree view.
Most places in Qt, a Search: field was added to the dialog.
Looks possible to buffer keystrokes and do a string search in Qt.

Default value is 400ms (even on Windows). Average typing speed of
200 cpm = 300ms per character = too close to 400ms when searching
the protocol name in Preferences -> Protocols.

 Wireshark supports quite a few protocols, which is reflected in the long list of entries in the “Protocols” pane.
-You can jump to the preferences for a specific protocol by expanding “Protocols” and quickly typing the first few letters of the protocol name.
