scojs CSS improved, extended and SASS'ed

SASS: CSS is now compiled using SASS, Compass and animate.sass to make
it easier to maintain and provide SASS users with the ability to
customise via variables.

Individual files: Users can include all css via scojs.css or individual
stylesheets per component.

sco.message.css: Animated background will be made possible via an
additional data-attribute. Added the CSS for that.

sco.tooltip.css: Tooltips are using :before and :after pseudo-element
to allow for tooltips with borders. A ".light" version added as well.

sco.panes.css: .slide is now using "translateX" instead of "left" with
some hacks to ensure that HD acceleration is enabled. This should give
better performance and a smoother transition. Some improvements made to
flip and a new option added: "flipX" to allow for rotation around the
x-axis.
