No actual functionality yet
Actual subtween functionality implemented
Added documentation for Tween.tween_subtween and SubtweenTweener
Implemented some additional functions
`set_ease`, `set_trans`, and `set_delay`
Documentation only for `set_delay` so far, since I have tested it
Removed set_ease and set_trans
Upon further investigation, the way they are implemented for Tween doesn't appear to work here
Fixed indentation in documentation
Reset subtween when parent loops
Fix return type of `SubtweenTweener.set_delay`
Add notes to documentation
Apply suggestions from code review

Apply some suggested changes
- Remove excessive documentation
- Add Tween constructor that takes in SceneTree
- Make `SubtweenTweener::subtween` public so that `Tween` doesn't have to be a friend class
Remove unneeded friend class SceneTree
Remove superfluous documentation describing subtween behavior

Early return from `tween_subtween` if the subtween is `null`
Implements godotengine/godot-proposals#5141.
Adds a new get_loops_left() function to Tween, allowing developers to
reason about how many times a tweening sequence will repeat and whether
to expect finished or loop_finished as the next signal.

As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
Implement built-in classes Vector4, Vector4i and Projection.
* Two versions of Vector4 (float and integer).
* A Projection class, which is a 4x4 matrix specialized in projection types.
These types have been requested for a long time, but given they were very corner case they were not added before.
Because in Godot 4, reimplementing parts of the rendering engine is now possible, access to these types (heavily used by the rendering code) becomes a necessity.
**Q**: Why Projection and not Matrix4?
**A**: Godot does not use Matrix2, Matrix3, Matrix4x3, etc. naming convention because, within the engine, these types always have a *purpose*. As such, Godot names them: Transform2D, Transform3D or Basis. In this case, this 4x4 matrix is _always_ used as a _Projection_, hence the naming.
