Added filtering ability to TableRowCollection. Show details rows now reappear when rerendering if they were shwon before. The current implementation of this is a bit crap, should really clone them out and put them into the tbody we are going to insert so the rendering doesn't jump.
initial implementation of filtering
detail row is now customizable. Reworked redraw to no flicker on detail row, we no add back any detail row in the redraw method before anything is rendered which eliminates any redraw events which caused some horid jerking. Creating detail row can now be passed into options, it takes the values array (dump it) to know what to draw as well as the row (not used in the default implementation), must return an html string so it's optimized, no jquery objects are used in individual row rendering for speed
bug in sorting where sorting is reversed
added filtering plugin to meteor package.js
