[MoM] Eaters can't attack through walls

[Standing-Storm]

Summary

Mods "[MoM] Eaters can't attack through walls"

Purpose of change

It was too much.

Describe the solution

Remove NO_PROJECTILE on their drain attack.

I also set up a system where they can attack through walls if you're within 5 squares, but thanks to the way the KEEP_DISTANCE flag works they will never do it. Maintaining a 15-square-buffer is their first priority and if they can't do that they'll just flail around for a while without attacking. RedMisao discovered this is true even if they have the CORNERED_FIGHTER flag, which seems undesirable.

Describe alternatives you've considered

Testing

No more eaters hitting through walls.
