First Update: New shield, wave selector and scoring system

Hi everyone :) The first update should be coming now.

Here's what I added

- New model for the shield (not entirely finished, but it looks cool, and you can see through it) - Texture update for the arena (again, not finished, but it looks better) - Wave selector, you can finally select which wave you want to play at among those you have completed. Just throw your shield at one of the wave selectors - Shield grabbing update: The shield is now grabbed at the end by the hand, which makes it somewhat easier to throw. Please tell me if you like it this way. I will probably add an option to switch between the two modes in a later update. - The bug where enemies sometimes glitched on the outer walls shouldn't happen anymore - Decreased a tiny bit the time that the enemies portal takes to make them spawn - Shield physics should be a bit better than before - Scoring update: Enemies now give more points as you progress in waves, and you have bonus points at the end of each waves. After each wave, the enemies give 20 points more (this is multiplied by combo) At the end of each wave, you get a bonus of 100 * number of the wave points. This is to get more score to players at higher waves.

Example

At wave 10, killing an enemy will give you 50 + 20 * 10 points, so 250 points At the end of the wave you would get 10 * 100 bonus points, so 1000 So let's say you start at wave 10, and kill 10 enemies, you'd get 3500 points. That way you are not punished by starting directly at a higher wave, since higher waves give a lot more points than previous ones.
