Riot bot and e-handcuffs improvements

* E-handcuffs add more pain when user moves. (KA101 idea).
* You can use EMP to disable your handcuffs. e.g. directional EMP bionics, EMP grenade...
* bio_shock bionics can disable handcuffs.
* Electrical Discharge from bionics (failed cyborgs bonus) can slightly damage handcuff's battery.
* Artifact or bionic stops electricity from handcuffs.
* Uncanny dodge - sometimes you can to get out of handcuffs arrest. Handcuffs will added to your inventory and you can run away while Riot bot read your rights.
