internationalization of user visible strings

[matthewrmshin]

CLI help text can do with i18n as well. E.g. my environment of svn would do this:

$ LANG=pt_BR.utf8 svn
Digite 'svn help' para uso.
$ LANG=en_GB.UTF8 svn
Type 'svn help' for usage.

Being realistic we aren't going to manage this for 8.0.0! Bumping to some-day unless there are any objections.

foo = _("Task Tag") where Python figures out a mapping for the string from some place.

We'll try and find if anyone is interested.
[@hjoliver] in having it done, and in doing it for us. It isn't a complex programming job.

This is being done in https://github.com/cylc/cylc-web, which has already support for i18n. We could mark this as superseded, but only if we assume having the command line in English only is OK.
