Release notes presentation

[Nir Lisker]

Hi,

I posted the release notes for OpenJFX 14 on Reddit. The top comment [1]
complained about the presentation. Maybe on openjfx.io the Release Notes
link could show a more "friendly" summary with a link to the detailed
table. I suggest:

1. Including only changes that matter to the users of the library with
separate sections for new API and for (non-internal) bug fixes.
2. Highlighting significant changes.

Some example bug fixes to include:
- TableView, ListView: unexpected scrolling behaviour on up/down keys
- DragAndDrop no longer works with GTK3
- Window order is not correct when Modality.WINDOW_MODAL

Don't include:
- [WebView] Sub-resource integrity check fails on Windows and Linux
- javafx.web build fails on XCode 10.2
- Cherry pick GTK WebKit ___ changes

Enhancements to include:
- Add support for e-paper displays
- Add exclusion scope for LightBase
- Point2D and Point3D should implement Interpolatable

Don't include:
-  Color, Point2D and Point3D's fields should be made final

Thoughts?

- Nir
