Add Keychain plugin for Controls tab (#15)

* Add modified Keychain plugin for future Controls tab

See https://github.com/Orama-Interactive/Keychain/tree/4.x
Added Events autoload singleton for global eventing namespace
Added Events.Options for global options functionality

* Add Controls tab via Keychain plugin
Use Events.Options for save, load, and reset of settings
Separate OptionMenu tabs into scene files
Add locale saving and loading
Refactor SettingNodes scripts for more generalized use
Remove random prints
Remove useless spinbox signal connection
Make Resolution consistently use Vector2i

* Implement Godot project overrides for resolution and window mode

	Overrides are necessary as Godot does not load resolution or window mode on startup, so an override is necessary to ensure this happens.

Add null checks to SettingHSlider and SettingOptionButton

* Fix incorrect resolution value in ResolutionSelector

* Correct project settings override behavior in editor

Godot normally tries to overwrite the project settings in the editor, a template feature tag must be used to prevent the editor from overwriting the project.godot settings.

* Fix Orama-Interactive/Keychain#8
