Update 0.6.0: General balancing

This one is a bit smaller update but I wanted to get it done for a game jam. Next up I'm going to work on upgrades for the player's cabin and then the main story of the game, the war between the gnomes and the goblins.

This update includes:

• A big amount of small balance changes for quests, prices and effects.
  • this took most of the time, hopefully it makes the game easier to get into and guides the progression.
  • this also included some background work for upcoming story update.
• Picking ingredients is no longer instantaneous and has a little effect depending on which tool is used. Should 'feel' better.
• Some new status effects
  • teleportation, takes you to the place where the potion was brewed
  • invisibility, makes you invisible. For now, this is just for fun.
• some graphical updates
• as always, many bugfixes
