Reintroduce Diff::LCS::Change#to_ary

-   This required some level of code remediation in the main library, but all
    tests now pass:

    -  Patchsets are now internally flattened one level explicitly, rather than
       using Array#flatten. This ensures that only the outer patchset array is
       flattened.

Fixes #48.
