Endermites spawn from thrown ender pearls even when doMobSpawning gamerule is false

Confirmed.

Somehow to me I threw a ton of enderpearls.
none spawned. neither with it set to false/true!

Can confirm spawning with enderpearls. One endermite even killed me, because my health was drained due to the enderpearls.

Turns out there's a tag for Enderman called "EndermiteCount". When the value is 15 or higher, Endermites will no longer spawn. There's a separate bug where ghost endermites will appear, but they don't actually exist. Example:

/summon Enderman ~ ~1 ~ {EndermiteCount:15}

However, there is seemingly no way to prevent endermites from spawning via enderpearl usage. For adventure maps, we can fake this spawning since enderpearl usage can now be tracked, so linking the default endermite/enderpearl spawning to the "doMobSpawning" gamerule should work out.

I think for now it may be easiest for map makers to have a command block performing /kill @e[type=Endermite]. They're barely functional as a mob anyways.
