added icon for owner in group index
although once i implemented it im not sure how much worth it is.
it doesnt click through to group details yet
group index clicks through to group details
can duplicate expenses, sort of...
the existing expense attributes are passed to new expense page but skips to existing expense display page. if you browse back a page you have a prefilled NEW expense form, click create and new expense is created
