Version 0.15 Update

Changelog:

• Improved grappling hook collision detection and performance cost
• Grappling hook now rotates around the player while it is active and not attached to any obstacles
• Aim Indicator and Grappling hook are now painted in their respective team colours
• Decreased Aim Indicator speed significantly

Based on our current feedback, we decided to add these changes to make the Grappling hook a bit more intuitive and slightly easier to use.
