Add function and alias to help code review

Add following aliases:

- gmf: Show the changed files from base branch to current branch
- gmfn: Similar to gmfn, but only contains the name of changed files

Add a function:

- greview: Open all changed files in vim. Map <leader>gd to show the
  diff between base branch and current branch.
