Optimize db again

[coyotte508]

Make all_moves be loaded recursively: Moves from gen 1 are merged to gen 2 moves, and same between gen3, gen4, gen5, gen 6 moves.

So in the python script only add moves for new gens when they aren't in the older gen. Also fix pokemoninfo so that moves between gens are combined. (aka pokemoninfo.moves(poke, 5) will return moves from gen3,4,5 combined, using a .concat probably)

Another necessary optimization is to use default values a bit more often, for example, in pokes/genders.js, many entries have the value 3.

gzip shreds through that kind of data, but it's still not ideal.
