Create basic map scene

[gioragutt]

Basically we need a unity Scene which has the following attributes:

• It's a circular or rectangular map
• It's surrounded by some sort of barrier
• It has several (2+) points that can be spawned in - some place the teams/players can respawn after death or something
• It has some walls or something that make up some paths to move from place to place in the map. These places can be used as special points where Mobs sit.
