Add Pocket Camp music (Sunny, Rainy, Snowy)

[LupusHacker]

Pocket Camp was pretty forgettable in terms of gameplay IMO, but I stilled liked the "hourly" themes. And it was still pretty fun to play- although not for long periods of time.

Considering there was only three types of environment music (Sunny, Rainy, Snowy) along with the 4 time differences (morning, afternoon, evening, night)- I think it would be pretty easy to implement. It would get a tad annoying to listen to the same music for 4 hours at time before a transition, but it would still be a cool option. ^^
