Subject: Add initial implementation of having erl_tidy print to screen instead
 of writing to the file provided. The reason for this is that you may want to
 have an intermediary step between saving the tidied file and using the
 output.

Use-case personally is wanting to integrate
erl_tidy into emacs and tidy buffers, overwriting
the current file is generally not how this works
in emacs with source code tidiers.
