Error messages are written to stdout rather than stderr

[liulong0118]

As titled, error messages like "### Error writing out TS packet data: XXX" are all printed to stdout not stderr. For an old tsplay I used before, which was built from source code of 5 years ago, error messages were printed to stderr and normal outputs were written to stdout as expected.

Is this change intended or accidental?

Well, I found that the fix to this is obvious, so I just created a simple fix and the pull request #34 . Hope this is easier for you. Please have a look.

Thanks!
