1. Changed the P;datatable to P;datalist. Since datatable generates
table and handling the table from UI stand point is difficult compared
to div layout.
2.  Also changed the style in main.css to accommodate the changes done
in mailbox.xhtml.
3.  Added the rounded check box with styling as mentioned in wireframes.
4. Added the arrow on the right side of the list.
5. Linked the stylesheet main.css to the dispute page.
