Rework TUI: single-threaded curses, scrollback buffer, server menu

Browse Source

- All curses drawing on the main thread; stdin polled together with the
  ZMQ sockets, Ctrl-C only sets a flag
- Output kept in a 2000-line buffer and redrawn from it, so resizes keep
  the history; PgUp/PgDn and mouse wheel scroll it
- Messages without trailing newline continue the current line (status
  table columns arrive as separate messages)
- Too-small terminal shows a warning instead of exiting
- Start without arguments shows a server selection menu
- Colors on the terminal default background; version 0.9.0
