set file.encoding=UTF-8 as default in OS X runner
Moving some help files to mailer-plugin where they belong.
optionalBlock.jelly should only set a default value for help when field is set.
Otherwise Descriptor.getHelpFile(null) is called, which may produce a help page, but generally the wrong one.
(entry.jelly was already correct, so just making it consistent.)
