No Drop PlaceHolder

[GDmac]

This is a very nice add-on to sort a few entries in a category.

One little irk is that there is no drop placeholder to drop on.
When you start a drag all other items tug together, which
makes it difficult to exactly drop the item.

see drop placeholder:

This might have to do with the ui-sortable being
attached to a table, rather then a li. i tried styling
the .ui-state-highlight as mentioned in the example
with no luck.

I think this #6 fixes that.

@litzinger I think you can close this one now. :)
