v0.13

This is the biggest update so far and I'm positive it will be beat again very soon. I'm very happy with everything added in this update and I think it's a MAJOR step forward in getting this thing to look more like a real game. Next update will most likely be a technical one, I want to work on game saves, reimplement system generation, handling player death, etc. The game is still completely silent too, I might make an entire update dedicated to just adding sounds.

Changes:

• Added a wooden door that can be opened and shut.
• Added glass and glass background walls.
• Allowed for the ability for certain crafting recipes to require crafting "stations".
• Added the work bench, required for crafting basic items and tools.
• Added the furnace, used to craft glass and ingots.
• Added copper bar crafted at the furnace.
• Added copper sword and copper pickaxe that can be crafted at the workbench, stronger than flimsy tools.
• Added gold ore and gold bars.
• Added golden sword and golden pickaxe that can be crafted at the workbench, stronger than copper tools.
• Added iron ore and iron bars, which only spawns near the core of the planet.
• Added iron sword and iron pickaxe that can be crafted at the workbench, stronger than gold tools.
• Copper, gold, and iron bars can all be placed as a block. The copper block will slowly oxidize and turn green.
• Added a mallet that replaces the flimsy hammer, used to break background walls.
• Breaking a background wall with a hammer now drops a wall item, assuming the item for that wall exists.
• Added new ladders that can be climbed by right clicking. Missing an animation still.
• Added a pretty lily :) 
• Added gravel that will spawn in caves and falls like sand.
• Added a stone brick crafted at furnaces, as well as stone brick background walls.
• Added debug commands, press Enter to open it, and Enter again to use typed command.
• Current commands are as follows:
  • "fullbright" : toggles game lighting.
  • "give <id> <amount>" : can give the player any item currently implemented. Be advised that item ids are all over the place.
  • "ship" : spawns the ship at the mouse cursor. old ship spawn key has been removed.
  • "tick <amount>" : advances global time by a given amount of ticks.
  • "time" : prints current global time in ticks.
  • "zoom <amount>" : sets the camera zoom, 1.0 default.
• Rewrote how light layering works, no longer uses shitty green chroma key hack crap fuck
• New background system will allow for more interesting and dynamic backgrounds.
• New day / night cycle, make sure to make torches! Currently days last 10 minutes (5m day, 5m night).
• Forest planet and sun now have backgrounds unique to them.
• Game now supports semi transparent textures.
• There's a nice lil drop shadow on tiles and entities now. Subject to change.
• Water is now a more vibrant blue.
• The multi-tile code from last update was REALLY bad and I didn't notice until now. It has been fixed.
• Copper ore spawn rate has been tweaked.
• Praffin texture has been slightly tweaked.
• A ship in outer space will now align itself upright and can no longer be manually turned.
• Leaving a planet and returning will no longer cause tiles to render over entities.
• Fixed oversight bug where leaving water without holding jump would cause the player to jump anyways.
• Fixed oversight bug where planets larger than 64 chunks would place cave air at the incorrect height.
