speed fixes

removed custom selector, way to slow, went back to using a filter,
refined get parent code, much faster also.

removed animations, cannot be used on huge sets, unless i add smart
handling for very large nests ( there are no containers in tables so
each element must animate, and tbodys cannot nest )
added dynamic zebrastriping

Will auto restripe the table on tree folding, should be imperceivable, i
had to disable the background color transitions. Way to major to be
running that on all rows only for the hover highlight.
