Update to 1.16.0
    
    - Make true the default for “rememberinputmode”
    - Save “inputmode” to gsettings
      and add a “rememberinputmode” gsettings. This makes it
      possible to change the current input mode from the command
      line. And with “rememberinputmode” one can choose whether
      the last used input mode should be remembered and be used
      again when a new session starts or whether a new session
      should always start in table mode.

    - Skip cangjie5 and erbi-qs test cases if the tables are too old
    - Replace deprecated module “optparse” with “argparse”
