Bug 20520: Re-indent moremember.tt

This patch reindents the template for the patron detail page,
moremember.tt:

- Trailing spaces removed
- Indentation changed to a consistent 4 spaces
- Markup indentation made more consistent

To test, view the patron detail page. There should be no visible
difference before and after the applying the patch.

HTML validation before and after the patch should return the same
results.
