STATUS: A few features are missing.

I've been working on the Avalonia port of UndertaleModTool for a little while, so I decided to finally make a draft PR for it, in case anyone else wants to help. As discussed in #460 and elsewhere, Avalonia is probably the best choice, since it's multi-platform, works in C# and seems to suck less than alternatives. I tested the current build on Linux and it seems to work fine (except the performance).

Currently, I'm working on making it work as a sort of 'view only' UTMT, so those not on Windows can datamine games, at least. Of course, the architecture still has to be made such that we could later add editing functionality.

But, it is not complete yet. No, it is far from complete. Here's a TODO list of all the things I can think of that need to be done (but there's certainly more):

To support Mac with Avalonia, it's better to use NativeMenu. On platforms other than Mac, you can use the NativeMenuBar control to display a typical menu bar.

Keep it up :3

If there's any way I can reduce the workload by helping out then let me say hi!

@MayaChen350 Hi, you're welcome to send PRs to my repo for any features that are missing, thanks

[MayaChen350]

I'll do my best then! I switched to Fedora recently but then it happened I still wanted to make mods for Deltarune, so this PR could be an awesome/a literal life saver (and for other people)

Thank you
