Add ability to set submenu's popup delay time on mouse hovering

Browse source 
This allows to set delay time for the submenu to popup. Setting
this value low can increase responsiveness. If the popup menu is added
as a child of another (acting as a submenu), it will inherit the delay
time of the parent menu item.
