Nonviolent riot control bot...but it can arrest you [CR]

>Thanks for the hints participants you-know-who. :)

This bot has no lethal weapons, but he can get you so that you will reach out your hands and allow him to put handcuffs on you.

It emits relax gas like from closed PR https://github.com/CleverRaven/Cataclysm-DDA/pull/8488, so, its to hard to kill them. The gas is not invisible now.

It chasing you with speed of cop bot.

If you have weapon in your hands, it will sometimes shoot in you with blinding ray. Drop your weapon and stop!

If you have no weapon, robot asks you hold position, then it come to you close and arrest you.

Arrest:

* You can surrender. Bot puts *electronic handcuffs* on you.  About e-handcuffs read below
* You can resist. Then bot emits tear gas.
* Feign death (for good Int). If you have good Int and you lucky, bot will ignore you for some time. If you unlucky, you'll get a jet of tear gas in the face.

Give up, man...

###### Electronic handcuffs
Twohanded no unwield item. 
If you move with it, your hands will electrocuted. 
Riot bot ignores you with this item on hands. 
You can wait 1000 turns a while handcuffs discharged, you can use water to discharge it, or you can go and endure electrical discharges in the hands. 
E-handcuffs discharged faster if it shocked you.
Also it has sounds like siren. 

In pre-cataclysm time bots puts handcuffs on offender and offenders had to wait, when they will be taken by the alive police.

After discharging you can unwield this item, and you can wield it anytime to avoid bot! The bot will think that you have already been arrested.
Dodge 8 implies that the riotbot is a high-level gymnast or similarly acrobatic--it's a *very* high level generally and especially for a bot.  Increasing armor is probably the way to go if you want a bot to be tougher to fight.  (I'll alter this in the merge.)
