Cleanup Git history to remove unwanted files

I recently had to work with a Git repository whose modifications needed to be ported to another repo. Unfortunately, the repo had been created without a .gitignore file, so a lot of useless files (bin/obj/packages directories…) had been commited. This made the history hard to follow, because each commit had hundreds of modified files. Fortunately, it's rather easy with Git to cleanup a branch, by recreating the same commits without the files that shouldn't have been there in the first place.
