Make mush gnomes check if they can spawn more often

[grm9]

Currently, mush gnomes spawners test every 10 seconds if there's a player within 5 tiles away from them and if there is, spawn a gnome, but a player is likely to walk past the spawner by the time the test happens, even if they were in it's range before it happened, especially if they have any speedboosts e.g. beefalo or were on the edge of the spawner's radius, so i would suggest making them test at least every second instead, because currently it isn't rare to only see 0-2 mush gnomes after going through the entire biome even though there are always around 5-6 spawners. This wouldn't cause much lag, since they only test while they're loaded and i have never seen a world with even at least 10 spawners, but would make people see mush gnomes more often
