It wasn’t applying the transformation jid→filename used in log_message

Separate log items in two different classes instead of just trying the
length of a tuple

Also don’t handle logger fds outside of Logger, and mark private
objects and methods.

Make the "default" parameter optional and thus move it to the end of
the command with the other optional parameters.

And change all the calls.

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

.

(thanks eijebong)

Now everything in the logs is in UTC time, and is converted when read

(also, actually return the logs after loading them instead of not doing
anything)

config.get('option', 'value').lower() == 'value' is just ugly and
stupid, especially for bool.

One if in basetabs:556 was also missing a comparison, leading to True
whenever the option was set.

(new typ value)

- log_errors option, true by default
- errors go in log_dir/errors.log (so $XDG_DATA_HOME/errors.log
    by default)

This should help a lot for debugging, and provide a way for people
to easily give debug traces without useless or personal infos.

Archiving old logs is recommended before running this update,
just in case.

(and add the pep events and invites to it)

- Do not crash because of low disk space
- Notify the user whenever it happens
- A few functions now return a boolean instead of nothing
- Config.silent_set is Config.set_and_save without toggle and returning
  strings. It is used whenever we don’t need set_and_save
- Config.set_and_save now returns a tuple (that can be passed directly
  to core.information())

TODO: display the precise error to the user (instead of “unable to…”)

- Refactor the message handlers to be more readable
- Add a group_corrections tab-specific option (#2229)
- Fix issues with /correct in private tabs and conversation tabs

and do not read the whole log file for the last lines.

(instead of chaos)

- New option load_log defaulting to 200 to indicate the number of lines
  to be loaded
- It’s still very raw, and the format of the message does not match the
  format of the normal room history, for example
- Works in the Private chat, MUC, and Conversation tabs
