growth

Added a new ability to grow the sizes of trash. This will require a special resource in the next update and will require unlocking, but for now its available immediately.

Adds:

• Expand trash ability
  • this took awhile due to having to account for "all"(that i could think of) the things that can go wrong with growing an item
  • standing on a trash while growing will stop growing when your head reaches ceiling
  • trash will stop growing when encountering a ceiling
  • a trash on top of a trash that is growing will self destruct if in contact with a ceiling. this includes multi story stacks of trash
• start of new room
• more interactions with zero g
  • special particles
  • shots are affected
  • trash is affected
• changed main menu a bit
• made missile creation and pong playable without power
  • these still won't auto play without power
• make missiles more accurate by adding hit detection on their flight path
• did some other things that i forgot to track
