👋 Hello and happy New Year!

I've got a slightly bigger update to kick off the new year.

Changes:

I changed the program's design a bit. Colors from the old "Shadow" theme are now the default.
(⚠️❗ If you were using the program before, SkEditor won't automatically update the default theme. In that case, head to settings -> Personalization -> Theme, click the "Open folder" button, close SkEditor, delete the Default.json file, and restart SkEditor.)
Added a theme editor in settings.
Introduced an early prototype of code completion, which you can try out by setting EnableAutoCompletionExperiment to true in settings.json.
Added hex color highlighting in text.
The Marketplace can now install "packs" that include both syntax highlighting and themes simultaneously.
The Marketplace can now install more advanced addons using external libraries.
Fixed #8.
Fixed #9.
Fixed a crash that could occur when the theme wasn't loaded correctly.
Fixed a crash that occurred when having two identical addons.
Added the Skript addons menu in the Analyzer and the option to choose custom Java version.
