Error: Both data.yml and /private/tmp/.moban.cd/data.yml does not exist

I intended for the error message to be printed (rather than raised as an exception) just to let the user know that those files do not exist, because the command moban -t abc.jj2 implies that they want to use the default data.yml file - then, if they don't exist, moban will try to use environment variables.

However, I can remove that error from being printed if you want.

Yep, changing it to "info" now.
