GHC-like line snippets in warning messages

Currently, warning messages only contain an abstract representation of the problem in the user's source code:

..\curry-playground\MultiBranch.curry, line 4.5: Warning:
    Pattern matches are potentially unreachable
    In a case alternative:
      _ -> ...

It would be nice to have a GHC-like message printing the relevant line(s) in the source code:

..\curry-playground\MultiBranch.hs:6:5: warning: [-Woverlapping-patterns]
    Pattern match is redundant
    In a case alternative: _ -> ...
  |
6 |     _ -> 4
  |     ^^^^^^
