Fast Boss Transitions, Costly Attractor Fix, and DB migration

Finished migrating the demo data into its own database, allowing "balance snapshots" to exist within the same client. This should not change anything, but if you notice anything weird, let me know!

Fixed the Costly Attractor Nightmare base

Added a "Fast Boss Transitions" toggle. This speeds up the boss death and healthbar refill animations substantially. You can find this in the options menu
