Randomizing initialization of velocity
Adding the ability to eject Blobs

We're conserving mass, but not velocity.  Created a utility function for normalizing vectors as well.
Cleaning up console access to `space` and adding arbitrary # of initial blobs
Making the Space simulate and update all its blobs
Updating code to use property accessors
Highlighting the first Blob, 'You'
Adding a Direction property derived from the Velocity, along with an indicator for Me

Note that the position is not updated with the velocity if the velocity is zero.
