    Handle utf8 in JJB

    JJB didn't actually handle unicode data very well for a couple reasons.
    First the local yaml loader was loading files into yaml as strings
    instead of unicode which we should just go ahead and do because yaml's
    built int loader loads utf-8 by default (and we don't override the
    default). Second we need to do parameter substitution on unicode and
    regular strings so change the substitution typecheck to use basestring
    instead of str. Finally we need to use UTF-8 as the encoding when
    emitting XML so do that.

    Add tests to actually test this in the yamlparser tests. The addition of
    these new tests comes with a little bit of cleanup in the test classes
    to make sure we load unicode files as utf8 more consistently.
