Staff catalog search form uses placeholders instead of labels

[Stephanie Leary]

In the staff catalog search form, most form fields lack labels. This requires users to remember what the field was for once the placeholders disappear after they've started filling in information. It also causes problems for screen reader users. Bug #1831489 describes the same issue in more detail for patron-facing screens.

Branch forthcoming.

Thanks, Stephanie and Susan. Good accessibility improvement, and the styling of the labels looks really nice too! Cherry-picked into rel_3_10 and above.
