This is an attempt to fix #573. Secondary sort column is provided for in the documentation but didn't work. Keep track of sort direction for any sorted column. Need to add a test for this feature. No doubt class state and method arguments could be cleaned up.

I made this set of changes to permit multi-column sorting as I thought it should work per the existing documentation. That is, you can call sort() on multiple columns with the prepare parameter set to true, then call sort() with prepare=false to execute the sort. Further, you can now specify the sort direction for each sorted column. The serialize() function now returns an object that can be used to restore the state of a table that was sorted on multiple columns.
Testing...I have been too busy, or lazy, depending on how you look at it, to write tests for this. But it is working in my application, which redraws tables all the time using the restore() function, and uses the presort feature to sort by date in addition to the selected column.
The presort and restore features have not been exercised very much with more than one extra column.
