Demo Update -- 0.7.4

Update time!

Patch Notes for Demo 0.7.4:

[h3]New Stuff & Tweaks[/h3]

• Added an option to invert the X (horizontal) axis while using the photo camera.
  
• There is now clear indication when a specific animal has (or hasn't) been photographed before.
  
• Wildlife will now show indicators after they've spawned in, but are currently obscured or out of view, letting you know that they'll be in view shortly.
  
• Right-clicking the photo camera now pulls up the 'camera help' window (in addition to the '?' icon in the upgrades menu).
  
• You can now take the photo camera much lower to the ground, allowing for more dynamic angles.
  
• Added additional indication that a 'Level Up' is ready (this continued to be a source of confusion for some players)
  
• Reduced the default volume of the music & radio (of course, they can still be fully adjusted within the Options menu).
  

[h3]Bugfixes[/h3]

• The 'New' alerts on various objects and menus weren't properly persisting between levels.
  
• Fixed a bug where the 'locked' icon on the XP bar wouldn't always show after reaching max level for the demo.
