New general update

So, in this update I added explode able barrels to the game as well as a movement speed upgrade path. The rest were small fixes and updates.

Exploding barrels help with combat in general as they allow you to get kills by AOE instead of just the normal methods. These also align with the story, and that will be expanded more on later. 

The movement speed store upgrade helps with combat and abilities and makes sense to add with the way the game flows and feels. 



All items :

• Added explode able barrels
• Adjusted explosion scale and damage
• Added destroyed car versions of all cars

• Added movement speed upgrade to store
• Reconfigured store pricing

• Fixed some broken ui buttons
• Added consistency to some items
