Ultra Sun/Moon update

Ultra Sun/Moon stuff is (a little belatedly) in the db! Beware minor spoilers!

• The main point, of course, is all the new moves everything learns; here's a huge list!
• Dusk Lycanroc is available for any Rockruff to evolve into; it isn't treated as anything special.
• All the stuff I left out last time (UBs, Necrozma, Marshadow) is the db now, along with all the new spoilery stuff.
• If the newly-added Pokémon's icons are appearing as Bulbasaur or something, refresh manually. (Their big sprites are still missing; I'll get to that later.)

EDIT: Alright, all the sprites should be in!
