Version 0.1.15 hotfix

• A quick fix for two co-op problems that came in with 0.1.14.

FIXES

• A friend's walking Pokémon is no longer copied over and over. In 0.1.14 a friend's Pokémon left a long line of copies behind them, each with a "…" bubble. Now each friend has just their one Pokémon walking behind them.
• No more stray trainers or pins when you play alone. A world saved while a friend was nearby kept that friend and the copies of their Pokémon in the save, so starting it alone showed an extra trainer standing still and blue pins where the Pokémon had been. Saves no longer keep them, and a world already affected cleans itself up the next time you load it.
