[0.4.2] Autoaim toggle issues

[Gammli]

Changing the autoaim setting while in an active game in Duke 3D, RR and Blood does not work, you need to start a new game or load a save for it to apply.
Interestingly, this works correctly in Shadow Warrior when switching from 'On' to 'Off' while ingame, and does not require restarting.

However, instead Shadow Warrior does not seem to treat the 'hitscan only' option correctly, and instead autoaims with both missiles and bullets when that option is selected.
Duke 3D functions properly in that regard, as does Blood and RR.

Thanks to leodoom85 on Discord for bringing my attention to this.

Just finished investigating this a little in NBlood v1.01, Rednukem, VoidSW, and EDuke32 (build from Feb 11th).

This does not appear to be inherited from any port, the autoaim behavior updates in real time after the setting is changed in these ports. Can't say anything about the "hitscan-only" setting in SW, however, got nothing to compare it with - VoidSW and SWP have only on/off toggles for it, and so does Redux if I'm not mistaken - just like vanilla I guess.

Ugh. Classic Build hack job. It was coded right into the menu, that's where it got lost. I left a note in the CVAR but never followed up on it because I didn't realize that it was even needed for locally changing this.
