Leaderboard reading without crashing

I've been getting crashes while closing the editor and while building packages. These are often during the leadboard system destruction.

Turns out my simple implementation using a static FOnlineLeaderboardRead was flawed. My guess is that the game module gets torn down before the editor module leaving the editor pointing at now corrupt static data. To alleviate this I've put them on the heap for now.

IOnlineLeaderboardsPtr leaderBoards = pSubSystem->GetLeaderboardsInterface();
if (leaderBoards.IsValid())
{
if (!leaderBoardRead)
{
leaderBoardRead = new FOnlineLeaderboardRead;
leaderBoardReadRef = new FOnlineLeaderboardReadRef(leaderBoardRead);
}
if (leaderBoards->ReadLeaderboardsForFriends(0, *leaderBoardReadRef))

I really must look up any sample code on getting these systems up and running, the documentation is very WIP and there are probably a load of gotchas like this that are not apparent to my nOOb eyes from what documentation exists.
