New Character class!

I put in a new character class, enjoy!

Mechanics:

-New character class: The Assassin:
 ->Does a lot of damage but is very sqishy
 ->Normal attack is very fast, on the third attack he uses both daggers at once, dealing massive dmg
 ->Skill1: Throwing three shuriken that don't get destroyed on hit

 ->Skill2: A poison bomb which deals a lot of poison damage to everyone running through it

 ->Skil3: Making yourself half invisible, enemies that haven't attacked you yet will ignore you, enemies that have already seen you stillt attack you.
  Makes it harder to see the player in pvp.

 ->Pressing the interaction key on a wall or tower allows you to climb it up

-You can now change your color in the campaign
-There is now a sound for taking damage
-There is now a sound if buildings and spawners get destroyed
-You can now hide the aim cross as well
-There is now a running animation

Balancing:

-The warriors first and second skill deal more dmg now

Bugfixes:

-The Candy Canes now spawn only on the christmas map
-The game continued after the statistics showed up
-The sound of the church was way to silent
