Add a web config option to control toolbar button display:
- icons+text (default): show both icon and label
- icons: show only the icon, hide text labels
- text: show only the label, hide icons on buttons that have labels
Body class (btn-icons-only / btn-text-only) is set in getBodyTopHTML() and
CSS rules in skin.css toggle visibility of .text spans and icon elements.
Add title tooltips to console.php buttons so they remain usable in icon-only
mode. Migration appended to zm_update-1.39.4.sql.
