   - Added -q, --quiet (speaks for itself)
   - Added -l, --loglevel subsystem=LEVEL,subsystem2=LEVEL2,...

 - Avoid unicode problems if we set a profile
 - Move fingerprint checks from _register_handlers to _connect_success
 - Some enhancements to fpr checking code

 - In verbose mode, print encodings. (Especially for Windows users who don't have Python) (gajim.py)

[PyOpenSSL]
 - Fix 100% CPU usage and hanging connection when server closes connection on us. (c/x/transports_nb.py)

 - this → self (c/x/transports_nb.py)
 - Call _do_receive() once to collect error message from socket, when error flag is raised in scheduler. (c/x/transports_nb.py)

if print_time==sometimes : Show the day if needed also. Use locale for time format (do
not force
24h)
Delete a lot of unused locale variables (thanks pychecker)
del gajim.py useless global vars after use
configpaths.py : use self. not this.
