canto-{curses,daemon}: 0.9.{3,1} -> 0.9.{4,3}

Close #8884.
A very detailed changelog and discussion can be found here:

http://codezen.org/canto-ng/news/

This change was built locally and tested by me. There will be changes
noticable in the `canto-curses` interface since color support has been
reworked. For more details follow the hint in `canto-curses` or read the
changelog/manual liked to above. There also have been many
under-the-hood improvements which can also be found in the link above.
