Move .INI settings to Project Settings and replace autoloads with dependency injection

[bion33]

This merge request:

• Moves settings from the .INI file to project settings. This makes it more convenient for sighted people, and I hope it is at least just as accessible. The settings are put in project.godot under "[Accessibility]".
• Replaces autoloaded TTS instance with a single instance trough dependency injection, to keep the autoloads strictly for the game itself.
• Make loggin configurable, so it can be disabled to keep the console output for other things.

The settings are:

[Accessibility]

In_Editor=true
Logging=true
Speech_Rate=50

I got the inspiration for how to make the settings available in project settings from WAT-Sharp.

These were just changes which were convenient for me personally, so let me know if I should change anything :)

Oh, almost forgot to mention, I tested this on Godot 3.3

Thanks! I'll check this out in the next day or two. One question though. Part of why I went with the separate file approach was to separate enabling of editor accessibility from the project file, which is a part of the game. My goal was to enable collaboration without forcing everyone to use the screen reader in the editor, and to avoid accidentally committing and recommitting settings changes. Does this PR achieve that somehow? Thanks again, I do appreciate it!

I didn't think of that, this PR indeed does not achieve that at the moment. I've just tested moving the settings to the Editor Settings, and that works with minor changes.

Would that be a good solution to the problem or does it have drawbacks of its own?
