hi! just another real real quick hotfix to fix some stuff i forgot with the last hotfix, plus some stuff that was meant for 1.2 but should be stable enough to include now

changelog:

• fixed request system not loading correctly on some (existing? all?) saves
  
• forgot to add the layer for upload servers to the new interaction layermasks, the upload obj type should now actually be playable again (woops)
  
• new inventory background (blurred transparency)
  
• new grenade mechanics:
  
• doesn't automatically throw on hotkey press anymore
  
• press lmb or rmb to overhand or underhand throw respectively
  
• can hold button to cook the grenade
  
• while cooking, can cancel by either switching weapons or pressing r
  
• throws towards where you're looking now, instead of awkwardly to the left
  
• new explosion effect
  
• no changes to grenade damage/range/physics have been made, so the explosion effect is a bit too big right now
