Merge branch 'feat/erl_tidy_print_to_stdout'
* feat/erl_tidy_print_to_stdout: Added documenation for the new option describing what it does. 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. OTP-11632
