add syslog log handler as an option

[yeti9990]

it'd be nice to have the option of sending log files from script(s) to syslog. The init_logger should accept three (3) additional args and append a syslog handler:

• syslog_server
• syslog_port
• syslog_port

We might need to support:

• syslog_level in case you want custom level for the syslog handler
• syslog_facility as well

NOTE: we probably should NOT add this to the init_logger - instead we should have an add_syslog_handler() to keep things simple
