Minor update 4

I did some experiementing with enviromental hazards (traps etc..), but i will save those for later update as they need more polishing.

   Anyway here is small update with some bug fixes and balance changes.

• Fixed cursor not scaling with fullscreen
• Fixed hide/show weapon details button hitbox with fullscreen
• Fixed taking too much damage from rockets to shields when using shockarmor
• Homing missiles, Helmet, Shockarmor and Super Ability no longer appear to shops before lvl 7. (These items were feeling too strong in early game)
• Wolf Paws and Suspicious mushroom now give small bonus even at full health
• Weapons can no longer spawn in front of arena entrance/exit
• Some other small fixes
