Started implementing vertical alignment reboot. Refactored .group-mixed.with-checkbox.
Reverted normalize.less e1c6d8c096443f2e94396ab762c30428786b4241 and added textarea modifications to inputs.less.
Vertical alignment fixes on .group-mixed.with-checbkox.with-textarea. Fixed line-height in clamped text label as well.
Vertically align icons so they will not expand parent height.
Vertically centered content in list picker.
