Ease of use updates

This update follows up on some Discord and Reddit recommendations!

• Removed automatic turntable effect when zooming onto districts with Left-Click.
• Added a small sphere that indicates where your camera is orbiting around. This usually is not necessary for games that feature this kind of 'gods-eye' piloting, but because we can boom the camera up/down with Q/E, this can make things confused.
• Visually demarcated the Lower, Middle, and Upper wards of Sharn.
• Adjusted the tooltip / popup's pivot points to make it less intrusive.
• Minor art direction tweaks.

Roadmap

1. Finish tweaking camera rigs.
2. Improve district navigation with a clickable list and district type tags.
3. Implement major landmarks of Sharn as focusable elements (Morgrave, Cannith Tower, Terminus Station)
