Centered Fun

• updated to Swift 5 and latest MacOS
• upgraded WebView to WKWebView
• resizing the nethack terminal to the current games size so it can be centered on the screen - this does (sadly) not mean that the content is perfectly centered. In fact, we center the view the games player has. If the player has a super wide console open, we center that super wide console (which results in nethack visually being displayed more to the right). But hey, better than it always being in the top-left corner only

Now with less crashes

Overall this is a "quality of life" release. Things work similar as before, just nicer 😎

• I learned some more SWIFT and refactored the use of WebView in this project. Things should not crash anymore. (if they do, open an issue :))
• Added icons and a preview -- the settings pane is a much friendlier place now
• Character stripping on the nethack server made us see weird ?-characters sometimes. This is detected and worked-around now
• The terminal we open nethack in is now intentionally bigger than most screens. This should prevent accidental newlines when rendering nethack games

disabling previews as they crashed

In case you noticed, we jumped over the 1.0 release because i wanted the last release to be 1.0 but screwed up. So this is 1.1 🎉

It fixes a crash when previewing the screensaver in the preferences pane.

Here be dragons

This is the first release. If you find this version working (or not), I'd be grateful for feedback.
