Facility and Severity are undefined when prival is 0 #44
Description
In parse.js, function 'GlossyParser.prototype.decodePri'
when a message starts with <0>, then the returnVal.prival will be 0.
Then in the if statement 'if(returnVal.prival && returnVal.prival >= 0 && returnVal.prival <= 191)' it will always return false as returnVal.prival is 0. Then Facility and Severity will be undefined.
Please fix this bug.
