First post-jam update: fixes for bugs & annoyances

What’s new:

• Removed the sussy camera movement at the start of the level
• Revised item spawning logic; more things spawn around you
• Bugfix: stopped items (and trees) from spawning outside the level bounds
• Bugfix: stat bars could sometimes under/overflow
• Changed “hunger” and “thirst” to “food” and “hydration”, so now all bars count down to zero and optimally should be kept at max.
• Changed restart keyboard shortcut from R to N
