Preventing BrokenPipe error

[rlewicki]

I solved this issue by replacing all print! and println! macros with the ones coming from calm_io library which are stdoutln! and stdout! macros. They are basically doing exactly same thing print*! except it actually returns a Result instead just panicking.

This allows us to catch the result of a text outputting attempt and check for an error. In this case we want to catch std::io::BrokenPipe error and continue in a graceful manner.

Let me know what do you think about using this library, is this fine or would you rather solve this in a different way?

This fixes issue #18

Thanks for this! #95 was a solution to the broken pipe error. issue #18 is more about avoiding the use of print*(). I think that stdout() is a possible option.

@UlazkaMateusz I wanted to ping you. I know that you wanted to provide a solution to this problem as well.
