wip/twitmail 0.42 NetBSD

twitmail is a curses-based mail-like interface to twitter. It also can be used as a command line app for sending and receiving tweets. In both modes it remembers the last thing you read and only shows you newer posts (ie, it reports nothing when you have no updates to read). It'll collect all the new posts as well (up to a configurable limit), to ensure you haven't missed anything important.
