At level basic_cave collisions not working properly

[xet7]

From spadix at IRC Libera.Chat channel secretchronicles:

At level basic_cave, if you kick a shell towards a Furball boss, the collisions do not seem to work properly since the shell gets through the furball.

The shell is not programmed to change its moving speed when colliding with an enemy. This is because the shell, always, either dies or kills the enemy and moves on. I tried to fix this by changing m_can_be_hit_from_shell = 0 to m_can_be_hit_from_shell = 1 in furball.cpp, but the furball boss was killed even if it had "3 lives".
