update js and css to newest available version
styling based on sunburst, needed to adapt menu layout - see changelog
use link to render stylsheet since most of plone's styles do so. no upgrade step since this is a minor change and integrators usually reorder styles to minimize the number of groups anyway
update documentation, mention superfish since this addon is based on it rather than suckerfish. remove non workin link
this package need not be initialized as zope2 product
split up generally useful styling and plone sunburst specific overrides to separate css files. add upgrade step for installing css
alert integrators about ios issue
add comment from example css
