Dev branch

[LaserEyess]

Trying to do large changes without breaking stuff is hard. So, I AM GOING TO BREAK THINGS.

You're free to try this branch out (if I ever actually work on it, 0 promises, none), but just know that this is not release ready. In fact it's not guaranteed to work at all. The goals are:

1. GTK4: remove anything and everything that stands in the way of this, even if it's useful
2. Maintainability: on top of GTK4, use more .ui files, drastically reduce C code for custom objects, even if they're useful
3. Performance: Remove O(n^2) loops on torrent data, excise anything that's slow, even if it's useful
4. New daemon features: labels, groups, new json API

Once this is in a usable state I'll start thinking about backporting changes to TRG upstream. There is no guarantee I'll write a single line of code though, so don't get your hopes up.

Issues that will be instantly closed and ignored:

• "My favorite feature is missing!!!!"
• "This doesn't follow the GNOME HIG!!!"
• "The layout looks different!!!"
• "Minimize to tray!!!!"

Issues that will be taken seriously:

• It crashes
• Communication with the daemon is broken
• Data from the daemon is wrong (e.g., says a torrent is in the wrong state, has blatantly wrong information)
• UI elements are broken (e.g., press a button and nothing happens (maybe... I might just decide to delete the button instead))
