Twitpocalipse now!

Twitter uses a signed int as a message identifier. According to this web site this message ID will soon reach the maximum number that a signed int can contain. It may start producing negative numbers. Fortunately, Twitli doesn't rely on Twitter message IDs so it won't be affected. Twitli does use the DM message ID, but only to trigger the new DM notification. Worst that can happen is that these notifications stop coming.
