New Weapons and Waves

CHANGELOG:

- Added two new weapons: Compound Bow & Tactical Crossbow

- Added waves 6-11

- Lowered purchase price for Basic Bow, Crossbow, Stone Spear, and Binoculars

- Player vision increased from 6.5 on an orthographic camera to 8 on an orthographic camera

- Coins earned now slightly increases per wave

- starting coins increased from 1,000 to 4,000 for testing purposes

- I didn't explain this before, but the Weight stat affects your stamina regeneration speed. More weight = slower regen speed
