Extract photo mode to a reusable addon

[NathanLovato]

close #6

Tasks:

• Add gamepad controls
• Consider setting some input actions and registering them from the addon automatically to keep input code simple?
• Fix lag on mouse rotation
• Add ability to move faster with modifier
• Add key/input to control the base movement speed at runtime? E.g. scroll wheel

You may also be interested in https://github.com/Calinou/godot-photo-mode-demo, which I started working on as a reusable photo mode add-on for any game. It doesn't offer camera controls yet though: it's mainly focused on increasing graphics settings, taking a screenshot then restoring the previous graphics settings.

Thanks much for sharing Hugo. I'll def. check this once we're done with the release. We worked on a system for graphics settings too, to be able to switch profiles, but I'll check your code and see which would work best for us.

It's part of the little project trying to automatically pick graphics settings based on user hardware, a sample copy of which currently lives in a branch: https://github.com/gdquest-demos/godot-4-3d-third-person-controller/tree/feature/benchmark
