Title: Grouping achievements

For my game, I had multiple cases where a player could earn more than one achievement at once. I added a slight delay to the display of the achievement notification that allows for grouping of notifications Xbox-style. If multiple notifications are queued within a defined timespan, only one notification will be posted, reading "X achievements unlocked".

Developers just need to set the static `groupingWindow` property. Alert display will be delayed by this window time. If the window is 0, then there will be no grouping. The default is 0.
