Update `help_getOutput.sh':
- Rearrange `--update-output' and `--update-structure' options.
The first one seems to have preferences when less characters are
provided. For example: using this commit as reference, if you
provide the `--update' option to `centos-art.sh' script, the
`--update-output' will be used. Notice that the `--update'
option isn't set explicitly.
