Revert "properly move initial player spawning handshake stuff to componentized"

somehow this commit broke disconenct..reverting it piece-wise didn't work oddly.
gotta traceback and see what's going on here.

This reverts commit 8d4e5c5531ed775195eac557a3a71db8c20b1d8d.

Conflicts:
	src/network/packet.cpp
don't need playerviewport in spritesheetrenderer

set a nice default value for packetcomponent's id (entity id), so we know
right away that it shit itself before it shits itself even mor.
wow so apparently simply adding a healthcomponent makes it shit itself

just health though. any other component in any other order is fine. health,
despite being very similar to aircomponent, gets all the sadness :(
artemis tries a double free. maybe it's more cost effective for me to first
evaluate and then try and switch to entityx..it seems nice, maybe actually
tested better...
