Updated Pending Requests page, Request Trade page

Styled PENDING REQUESTS page, now contains a table of sorts for each
received "message," sort of gmail style. Need to add click-effects to
it (use forms?) so each table links to the appropriate message. Also
need to add "trade status" graphics to table (for trades that have been
"accepted").
Added "accept" and "reject" buttons to REQUEST TRADE page (for the user
who receives the trade request). Might need some restyling later.
