* 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
