With this change we emulate a case sensitive filesystem on top of insensitive filesystems. This means we correctly pick up case-only renames and throw a case conflict error when there would be multiple files differing only in case. This safety check has a small performance hit (about 20% more filesystem operations when scanning for changes). The new advanced folder option `caseSensitiveFS` can be used to disable the safety checks, retaining the previous behavior on systems known to be fully case sensitive.
