Fixes throw_at() to look nicely for xeno leap by adding the diagonals_first argument.
Removes useless gateway/Crossed and gateway/Bumped().
Changes throw_at() to use diagonal directions.
I replaced the atom variable "throwpass" with the LETPASSTHROW pass_flags
I readded hit_check proc to catch things getting on the thrown thing's tile during its sleep(1) (especially needed for mobs running towards the thing), the only other possibility would've been to add throwing checks in atom/movable/Crossed() (called after every move) and I don't think it'd be worth it.
I added the item var "thrownby" to be able to continue to log the thrower of the item when it hits a mob. It removes the need for a thrower argument in throw_impact() and hitby().
