Bug 2889 - templates should use [% IF ( loop.odd ) %] - Administration

Some scripts pass a template variable to facilitate an alternate table
row class for styling. Other use the 'IF (loop.odd)' construction. I
think we're at the point where the CSS3 :nth-child() selector is
widely-supported enough that we can do without template-based solutions:

http://caniuse.com/#feat=css-sel3

This patch adds such a selector to the staff client CSS and removes the
corresponding template markup from Administration pages. The last in
this series of patches will remove the redundant CSS.

Also in this patch: a few minor markup corrections.

To test, apply the patch and clear your browser cache if necessary. View
the following pages and confirm that alternate table row highlighting
works as before:

 - Administration -> Budgets
 - Acquisitions   -> Vendor -> Contracts
 - Administration -> Budgets -> Budget -> Planning
 - Administration -> Authority types
