Added pikachu and started with controller hierarchy

We will need to arrange a meeting on checking how we should implement
each hierarchy based on what objects are gonna be in the game
added stage colliders & minor updates
Beginning with net functionality

1. The controller hierarchy is to be refactored
2. photon now updates the pos and rotation by default. Its time to add a
SerialNetBehavior to pikachu in order to smooth shit up.
3. rigidbody issue to be fixed
4. animation issue to be fixed
5. controller holder -> update only if you arethe local object, else get
the received data fromthe network stream
