Randomizing attack damage value when attacking

[CarrotKutay]

We want the attack damage dealt to be a range between 2 values -> the damage done will be picked at random before attacking for each attack

Maybe we could add crittchance in percent and crittdamage multiplier value.... this feature would also be connected to stats progression of the characters experience and level feature. #7 #10 #13
