[dehacked] potential bugs to be fixed in MBF25

Quoting Ravendesk:

"""
but I remember multiple people complaining about bounces/touchy flags, this stuff is a total mess since mbf and needs a complete rework
another thing that I can remember off the top of my head is line action 1024 and similar only scrolling the front side of midtex instead of both sides
there were many problematic parts like this mentioned in mbf related discussions

Quoting @Enator18 [fabiangreffrath/woof#1654]

"""
Basically, for some reason that I cannot figure out by looking at the code, if you call either of the mbf21 projectile functions, A_MonsterProjectile or A_WeaponProjectile with a projectile that does not have the MISSILE flag set, ie for grenades and such, it will spawn with zero velocity applied to it. This is inconsistent with the behavior of the vanilla projectile code pointers, as they do apply velocity to non missile projectiles as can be seen with the Lee Killough grenade demo that came with mbf.

This bug is also present in dsda-doom and odamex, but it is not present in gzdoom.

"""
This is also DSDA-Doom and MBF21 spec issue.

Bug report: [doomworld], test WAD: scrolltest.zip. A potential fix is to move the reset of the MIF_SCROLLING flag somewhere else, perhaps when if (!(mobj->momx | mobj->momy))?
