1.2.0

• Add --unapplied-migrations and --applied-migrations mutually exclusive options
  in order to respectively lint only unapplied or applied migrations.
• When loading migration starting from a git ref, cross the found migrations
  with the currently loaded migrations in the project.
• Add --project-root-path which allows to specify the root path
  which is used for finding the .git folder. (thanks to @linuxmaniac)
