Implement score uploading on LBP3 Adventures

[Arcadius2006]

LBP3 adventures are supposed to save your score individually per level, but it appears that this feature is broken - pls fix!

Important to note: LBP3 uses POST /scoreboard/{slotType}/{slotId}/{innerSlotId} to upload scores to and GET /topscores/{slotType}/{slotId}/{innerSlotId}/{scoreType} to get the top scores of an inner adventure level, where the given slot ID is that of the adventure itself and the inner slot ID is that of the actual level inside the adventure.

Another important note: LBP3 doesn't send any play requests for story adventures, but when entering an uploaded adventure's level, the game sends a play request for the adventure itself, not the inner level
