Improve the Import dialog

[MewPurPur]

It's an abomination. I should look into whether it can just use the default OS file manager.

If not, it still needs better theming - but it's really hard to work with the Godot node, so I hope I don't have to fix everything myself.

I'll close this when I improve the theming of the dialog a little more.

it's still missing on the webbuild. I haven't checked the software build yet

I added importing with file dialog to web build in #515!
It just isn't in the online web-build of GodSVG because we're waiting for Godot to release 4.2.2 stable.

Meanwhile you can drag and drop files on the website or use the desktop build.

I just made a more up to date web build: https://kiisu-master.github.io/GodSVG/web-build/index.html.

If you are fine with an unstable experience and some of my random modifications (experiment with smooth scrolling), you can try using it.
