DWR Util new methods.

I have created a few new methods in DWR's Util class/javascript and am wondering if DWR is interested for me to submit them into the code repository. If you are, let me know how and I'll contribute my code in. Here are the following methods I have created:

1. addRowTop - adds a table row at the top of a table.
2. addRowAfter - adds a table row begore a given element Id in the same table.
3. removeRow - removes an individual table row for a given row Id.
