`/log level INFO|DEBUG|WARN|ERROR` is now available.
Looks like this solves a TODO (see removed comment in source) from 2013
:-)
Works only with default log file. Not with user provided log file during
start up via the -f parameter.

Until they fixed this:
```
Problem: the to be installed ncurses-devel-6.3.20220604-20.1.x86_64 requires 'libncurses6 = 6.3.20220604-20.1', but this requirement cannot be provided
Problem: the to be installed gtk2-devel-2.24.33-2.8.x86_64 requires 'pkgconfig(cairo)', but this requirement cannot be provided
Problem: the to be installed ncurses-devel-6.3.20220604-20.1.x86_64 requires 'libncurses6 = 6.3.20220604-20.1', but this requirement cannot be provided
not installable providers: libncurses6-6.3.20220604-20.1.i586[repo-oss]
libncurses6-6.3.20220604-20.1.x86_64[repo-oss]
Solution 1: downgrade of libncurses6-6.3.20220604-20.2.x86_64 to libncurses6-6.3.20220604-20.1.x86_64
Solution 2: do not install ncurses-devel-6.3.20220604-20.1.x86_64
Solution 3: break ncurses-devel-6.3.20220604-20.1.x86_64 by ignoring some of its dependencies
```
"" used to become " now it just becomes an empty argument.
Also if quotes appeared after a token started then if the number of
quotes in the token is n the resulting one would be a token with the
n last characters cut off, now it's fixed.

Messages would get duplicated when you chat with yourself, worse if you
had omemo enabled the duplicated message would say something along the
lines of "Your client doesn't support OMEMO". The cause was carbons
when the message was sent from another client, whilst it was a sent
and received message when profanity was the one to send it. This commit
ignores the carbon message in the 1st case and ignores the received one
in the 2nd.
