Merge branch 'Story66_Collision' into 'develop'

Collision branch merging to develop

# Change log
* Added yacht-mark collision and yacht will be pushed back upon collision.
* Added yacht-yacht collision and both yachts will be pushed back upon collision.
* Updated yacht map position initialisation. Yachts will all be spawned behind start line with a distance apart from each other.
* Added a collision visual alert when collision packet is received.
* Added two extra colours to support for 8 boats.

# Testing
* Junit tests for yacht-yacht collision.
* Manual testing for yacht map position initialisation
    * Yacht spawned apart from each other.
    * Yacht will spawn behind start line even if start line is different direction.
