Add more polished feedback for shooting

[Sebp23]

This means making hits a lot more meaningful by adding more visual feedback such as:

• Screen shake
• Slight time stop
• Idle animations

We have hitstop behavior! Customizable in the inspector for the gun object:

Update: Screen shake will be for every shot, and hitstop will only happen on the death of specific enemies.

Screen shake should be customizable for each gun

• [x] Screen shake every shot
• [x] Screen shake customizable for designers
• [x] Hitstop only on certain enemies
