New enemy levels, fighting styles. Introduction of Immortals & Finishing moves

I have added new enemies in the game which are the Immortals. These units are higher difficulty than the normal Persians in the game and they have a completely different fighting style. Along with that the regular persians which have different levels have also different fighting styles now. Level 1-2 easiest fighting style. They are stupid they just follow and attack. Level 3-5 strategic fighting style. These enemies evaluate where and how to attack. Level 6-8 Immortals, they evaluate before attacking and also they have special combos. Level 9 Immortal [ not yet implemented WIP ] these will have a completely different style of fighting and probably different weapons as well. Level 10 - Wizard [ not yet implemented WIP] Level 11 - General : kind of like a boss battle, they will be present in only few camps. [ not yet implemented WIP ]

I also worked on creating finishers for the player. If the player can time the counter, the enemy goes into STUN mode and where it can be countered.
