BREAKING CHANGE: The old preferences panel has been replaced with a brand new one
Preferences are now much simpler, full of visual illustrations, and should provide a much better experience. Pick between 3 styles (thumbnails, app-icons, titles), sizes, dark/light themes, high visibility options, and more!
* Replaced the NSCollectionView with a custom NSView. Benefit includes simpler code, and control over recycling logic.
* In cases where the user has many open windows, replaced the downscaling strategy with a scrollable view
* Added a preference: align thumbnails to the left or center
XCode project/workspace/configurations/target/pods have been in a mess for a while. Some changes done to address that:
* remove alt-tab-macos/ which was confusing
* ci/ becomes scripts/ as these can be used locally too
* added 3 xcconfig files to set aside important parameters so we stop passing flags around or modifying the huge pbxproj
