[AVL-64] Hotfix 0.0.5.3 Various errors

[hatfield-c]

The command actuator function needs to be placed after the task is executed, otherwise there is a jittering error during control cycles.

Also, the Assignment One pdf file lists the water color as belonging to "Road".

Fix the gas-value accelerator interface to remove jittering.

Have the Ego vehicle spawn directly on the road instead of on the platform.

Angle the Ego vehicle camera downwards so there is more visual information to work with.
