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

Hey everybody !

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.

Here is a video of the new immortals level 6-8
