Fixes#118
- changed almost all "print" into logger
- threads have nicer names
- logger can have configuration in "logger.dat" in the same directory as
"keys.dat", and the logger will pick the one named "default" to replace
the "console" and "file" that are in PyBitmessage otherwise
Example file for logging to syslog:
[loggers]
keys = root,syslog
[logger_root]
level=NOTSET
handlers=syslog
[logger_syslog]
level=DEBUG
handlers=syslog
qualname=default
[handlers]
keys = syslog
[handler_syslog]
class = handlers.SysLogHandler
formatter = syslog
level = DEBUG
args=(('localhost', handlers.SYSLOG_UDP_PORT),
handlers.SysLogHandler.LOG_LOCAL7)
[formatters]
keys = syslog
[formatter_syslog]
format=%(asctime)s %(threadName)s %(filename)s@%(lineno)d %(message)s
datefmt=%b %d %H:%M:%S
