Option to hide months/years where there was no activity
Says it all in the title really.
If you've got a year where there was only messages in April, then it's fine to show the other 11 months on the left-hand list... but instead show Jan-March and May-December as greyed list items (non-hyperlink) to help users see where messages actually are in that year.
Same with years, if there was no messages in that year then if...
a) there has been messages since that year - then show the year in question but greyed out (like explained with the months)
b) if there hasn't been any messages since that year then don't show that year (or any subsequent years) at all
