added modes to object (update) (#46)

* Added States for monsters and corpses

Now can properly identify if a corpse is interactable with a skill ( barbarian, necromancer)
Also getting states about monsters  : Exemple  Soul Killer with Conviction aura:   State  28 // conviction

Also can tell if monster has a state after you used a skill on it  Exemple:   State 56  Terror ( After using Barbarian skill Howl to fear )

Another Exemple  using Grief on Mephistos he now have  states :    2 poison
    52  Preventheal

will be very useful for further development.

* Added modes to player

Now accessible in koolo using : s.data.PlayerUnit.Mode

Those are Modes for player:
const Death: 0;
        const StandingOutsideTown: 1;
        const Walking: 2;
        const Running: 3;
        const GettingHit: 4;
        const StandingInTown: 5;
        const WalkingInTown: 6;
        const Attacking1: 7;
        const Attacking2: 8;
        const Blocking: 9;
        const CastingSkill: 10;
        const ThrowingItem: 11;
        const Kicking: 12;
        const UsingSkill1: 13;
        const UsingSkill2: 14;
        const UsingSkill3: 15;

        const Dead: 17;
        const SkillActionSequence: 18;
