Chase camera not implemented

[cjamierun]

The game has a camera, but it does not follow behind the player character.

Acceptance criteria:

• [x] Scene has a camera
• [ ] Camera chase script exists in the project
• [ ] Camera lazily follows behind the player character
• [ ] The view angle is isometric-ish

The original vision was an animal crossing-like style, so an isometric view is required.

A really primitive chase camera was implemented, and it works for testing purposes, but it's ugly, doesn't trail softly and is non-isometric.
