Added some comments
Added more classes to appender to prepare for the new groovy rule functions
Added a new Groovy method called "infoLog" which allows log entries within Groovy rules to be handled by the JobEventLogAppender class
Added infoLog to the binding on the GroovyShell execution. This allows the method to be available on Groovy rules.
A little metaprogramming to the linkService instance to make the current job info available to the class as a method called "getJobInfo"
