- Added 3 new properties and 3 functions to control them.

- Rippers will rip through anything with an equivalent ripper level, or if their level is between or on the min and max ranges.
- If no min or max is defined, it simply checks if the monster's ripper level is lower than the missiles.
- Functions: A_SetRipperLevel(int level), A_SetRipMin(int min), A_SetRipMax(int max)
- Properties: RipperLevel, RipLevelMin, and RipLevelMax.
- RipperLevel: Applicable to monsters and projectiles.
- RipLevelMin and RipLevelMax are only useful on monsters.
- By default, all are 0.
