[Foldit] Configuration for Camera Starting Position in non-campaign/intro Puzzles
This pr adds support for configuring the starting position of the camera in non intro/campaign puzzles. To configure the starting position the following should be added anywhere in .puzzle_setup fiies:
```
"cam_center" : "x y z"
"cam_eye" : "x y z"
"cam_up" : "x y z"
```
Where x, y, and z for each component are replaced by a position an individual making a puzzle can obtain by using the CTRL+SHIFT+ALT+V keybind and checking their log file. Not adding in these fields to a puzzle_setup file will produce the previous behavior where the camera looks at/goes to a constant position.
