Bug 23533: Reindent patron entry form (memberentrygen.tt)

Bug 23533: Reindent patron entry form (memberentrygen.tt)

This patch re-indents the template for patron entry/editing. It
makes only whitespace changes. It should have no effect on the behavior
of the page.

To test, create or edit a patron.

Test every aspect of the process. At each step the page should work
correctly. Including:

 - Adult patron
 - Child patron
 - Organizational patron
 - Quick patron add
 - Duplicate patron
 - With mandatory fields
 - With 'BorrowerUnwantedField's defined
 - With ExtendedPatronAttributes enabled
