- use the new PluginConfig.remove method to remove aliases
- do not do weird stuff when no args are provided
- do not flood when re-creating stored aliases

(still surgically, without touching comments or anything else)

also bump version, and add some gettext wraps

(also, it indeed needs to be a thread because opening
a fifo for reading is a blocking operation)

Will also allow a remove_in_file or whatever to remove options instead
of blanking them.

(SIGTERM, SIGHUP, and SIGPIPE for now)

TODO: implement the remove_option method from configparser

should take care of the sigpipe when no one is reading it anymore due to
broken connection

- also fix some erroneous comment(s)
- remove self.background which wasn’t set to something other than false
- fix the chatroom address (and the doc) in the first help message

wrap some curses calls with try/except block

might send too many stanzas when send_chat_states is false, but I don’t
care.

also remove some hardcoded stuff

and sets the default value to false, to keep coherent with the code.

- add a show_composing_tabs option, default value: "direct"
- todo: find a nice different color for this

(it now uses the theme)

- fallback to mediated invitations if only the bare jid is given to the
  command or if the jid does not advertise support

TODO: provide a way to send passwords

now the scroll is made with 1/3 of the input size every time instead of
fixed offsets

(one-line fix, and the others are for reformatting imports to be consistent)

and show a somehow helpful error message in this case

thanks gio

also clean up some newlines mess

Thanks, anonymous contributor

It was actually doing that for old python version but not recent onces

that was ugly

- now it should work properly
- add a COLOR_LOG_MSG theming option, used both for local and remote
