#1 Subscription item status

[John Rubier]

It would be handy to have some sort of status indicator
in the subscriptions table to indicate OK/Problem
feeds. Perhaps something like a column with a
red/yellow/green icon. green=last refresh ok,
yellow=refreshes failed, red=error in feed. Something
along those lines. And perhaps a tooltip on the icon
that displays either last refresh time or the error
that occured (like the error message that displays when
the initial subscription fails)
