TPAC: Reduce vertical space in results paginator

An unnecessary span element with inline CSS results in additional blank
vertical space being generated for searches with only one page of
results. Avoid creating the span (which would normally contain the list
of pages), move the CSS to the style sheet, and use ems rather than
hard-coded px values for the padding to adjust relative to the font
size.
