wrap pretty much all freemarker variables (i.e the data) in encodeHTML(data..). this fixes tons of bugs in the admin, like when stuff dissappeats after quotes, etc.. also add query_text, query_field, etc.. to the delete request URL so that after deleting a comment, you come back to the same place on your list.. also get rid of useless offset hidden parameter which causes a bug when searching and your offset is above 0
