About The Pull Request

Adds new mech that can be created from emaged fabricator. To craft this mech you need:

1. Emag Fabricator to recive Justice disgine(done this, fabricator will emit a text and sound signal that can reveal you).
2. You need to craft it like any other mech but you also need 8 telecrystals to finish constraction.
3. To board a mech you need syndicate access (traitor can get it by purchasing an agent card).

   Text:
   Health 200
   Damage 60
   Only melee attacks(can't attach range weapons(can't attach anything in his arms at all))
   Block chanse 60
   Speed - in safty mode 2.5 in combat mode 4.5
   Attack effects:
   In addition to damage, it has a 50 percent chance of cutting off an arm or leg (does not put you to sleep or give a knockdown
   effect when hit like regular combat mechs do).
   If a target in crit or stun makes a finishing attack instead of a regular attack, the mech says an epic phrase and after a second cuts off the target's head by dashing through the target.

Special actions(can't be used if mech in safty mode):

Invisability - Makes the mech invisible for 20 seconds. If the mech is pushed or collides with someone or if the pilot presses the invisibility button again, the mech will no longer be invisible and will go into a 5 second cooldown (the same will happen after 20 seconds). If you attack in invisibility, then instead of a normal attack the mech will make an AoE 3x3 attack 1 second after pressing (the attack will be accompanied by a sound and visual effect and for a second the mech will not be able to move, which gives enemies time to run away from the attack). Upon completion AoE attack, everyone( except peoples in crit and in stunned condition) in a 3x3 radius will receive 35 damage and a 25 chance of having one of their limbs cut off.

Charge Attack - Mech makes a dash towards the cursor at a distance of up to 7 cells, breaking all obstacles in its path. If the obstacle is a living person (and he is not in crit and is not stunned) then he will receive 35 damage and a 25 chance of cutting off a limb. Cooldown 5 Seconds.
P.S.
Also added emag_act on fabricator so you can put any new secret traitor mechs on it.
Also made the sounds of mech melee attacks to vars so that it would be more convenient to change them.

Also fix a runtime error where if you set something in the mech's max_equip_by_category to 0, the mech UI panel doesn't load.

Why It's Good For The Game

Adds a traitor mech with fun and interesting mechanics. This is a new mech with new unique abilities that turns the battle with you into a boss fight.
