Arkanoid Catch Logic

1. Each capsule must have lweapon b
2. Add ball->Misc[CAUGHT]
3. Add ball->Misc[OLDSTEP]
3. \

5. In ball.check_hitvaus
if it hits the vaus, check: if ( catch == cancatch )
    then
        if !launched
        b->Misc[CAUGHT] = 1
        b->Misc[OLDSTEP] - b->Step
        b->Step = 0

        launched = false

in movevaus, if !launched
    if b->Misc[CAUGHT]
        when launching

        b->Step = b->Misc[OLDSTEP]
        b->Misc[CAUGHT] = 0


        when launched = false,

if a powerup --other thananother catch-- hits the vaus, restore b->Step from Misc[OLDSTEP]
    this is why powerups all need a param of lweapon b

store diffrencebetween v>X and b->X when catching, and save it in b->Misc[CAUGHT_dist], then
when !launched, instead of the normal position on the vaus, reposition the ball, using this
