Brick Types

[phrb]

Implement different brick types:

• Size
• Number of hits to break
• Color
• Moving? (see Moving Bricks #14)

We'll have to create different brick scenes and create instances of those scenes in the "Bricks" node script.

We could group each brick type separately.

Then, each brick type script must have a function that is called by the ball when it detects a collision.

Brick movements will probably have to be implemented in each brick type's script.
