TPAC: Remove noise, misleading text from myopac/holds/circs/circ_history

There are many "class='hide_me'" elements that will never be displayed
and which are currently just extra bits to ship over the wire. Same for
the inline comments.

Also move most of the inline styles out to the stylesheet.

Also remove the explicit widths on the table cells; if the font size
changes or the translated text is wider than the table cells, then the
display will become comical.

Also remove explicit <br> tags from localized strings; given the
likelihood that font sizes and column widths will change, <br> tags
inside localized strings make very little sense.
