mapping all syslog priorities

[dbyron0]

It's useful for me for SEVERITY_MAP to provide a valid mapping for all syslog priorities. That way I can implement a --debug=[priority] command line argument and then call:

  @logger.level=(Lumberjack::SyslogDevice::SEVERITY_MAP.key(priority))

such that @logger.level ends up as a valid (i.e. not unknown) level.

Trouble is, there are 7 syslog priorities and 5 Logger levels. SyslogDevice.write needs a one-to-one mapping from Logger level to syslog priority, so I think I need a new data structure to map in the other direction.

I can define this mapping in my own code but it seems to fit well here...I'm a ruby noob so I'm not sure the best way to do this.

Thanks for your help.
