Fix implementation.
Merge master.
Modified accordion split sections for better html conformance.

The previous implementation allowed for accordions to be interrupted by
other elements like block grids.  Now the accordions do not contain a
block grid.  The separate accordion sections can be named and don't have
to be contained within the same dl.
Remove zoom:1

It's not required for IE8 and above
Don't consider unnamed accordion attributes as a group.
Lib Update: normalize.css v3.0.0 --> v3.0.1
Replace static inline-list margin value

Margin on inline-list always set to rem-calc(22), replaced with $inline-list-default-float-list-margin
Orbit: `min-height` for slides_container (instead of `height`)

Using `min-height` (with `position:relative`) allows the slide container
to get expanded, in case it contains elements of variable height (e.g.
accordions).
Orbit: remove `.animate-in` late (just before setting `.active`)

This fixes the animations, especially with `variable_height` handling,
where the slide content would slide in, but then disappear until the
final animation of the containers height gets done / is finished.
