gotext cli tool should mimic xgettext cli

[Pixdigit]

I know there is a lot to implement if one wants to copy the complete xgettext cli but I would at least implement the behaviour with reading in files. I.e. that the last argument is a filelist to be read in. I already made a fork and would implement that there. This would allow a tool like poedit to automatically extract strings from code.

Thank you @Pixdigit I think it's a good idea, I'vec assigned you this issue as you mentioned you'll work on an initial implementation for this.

I'll look forward for your PR.

Sorry for the late reply but I sadly don't find the time to implement this myself.
