v0.4.4

Found a bunch of kinda-critical problems in the initial release of the GUI, so I’ve made some updates:

• The settings for the build targets are now correctly applied instead of inheriting MP3 for everything
• A critical error in the encode pipeline will no longer cause the entire app to spinlock
• Fixed the “made with bandcrash” link in the player to fit modern <iframe> security policies

I’ve also done some tweaking to the build process to make it easier to do a build, especially on macOS, due to an annoying thing with how Python standalone application builds work on macOS. That doesn’t affect people downloading the app from here, of course, but I figured I’d mention it anyway.
