#32 Bugfix - assign categories with many parents

[chris gilbert]

On the assign category authoring step, there is
currently a problem when a category has more than one
parent. Because the javascript causes a single element
(the first one on the page) to be expanded, if you are on
the 'wrong' trail, then nothing happens (because the
category expanded by the javascript is hidden). As a
result authors have to trawl through the category
hierarchy trying to find the first instance of the category.

Initially we hoped to use sortKey to uniquely identify the
path the user is on, but unfortunately, that isn't unique
at the level we are expanding - it is only unique at the
level above.

This fix expands all instances of the category - most will
be hidden anyway. The only downside is that if you start
expanding an alternative trail to the category then you
will find lower levels already expanded, which may seem
a bit confusing.

patched on version 689
